As technology continues to shrink, more features are being packed into these small mobile devices, making navigation and ease-of-use more important. This week, I tested the Motorola ROKR E8, which costs $199 with a two-year T-Mobile service agreement and makes a real attempt to be more user-friendly. The device, which comes out on July 7, isn’t much bigger than a typical cellphone but its standout feature is its keyboard, which dynamically changes to accommodate whatever you’re doing at the time, revealing only buttons that would be of use to that particular function.

The secret sauce on the ROKR E8 is its keyboard, which changes when it’s used as a phone, music device and camera.

The surface of the ROKR E8 has no physical keys at all. In its off or resting state, in fact, it’s just a black surface with rows of tiny, unlabeled bumps. But this surface is actually divided into two: The top half works like a typical cellphone display while the bottom half projects virtual keys onto its surface and uses the rows of bumps to give these keys a physical presence.

When making a call or sending a text message, the ROKR’s surface displays a regular phone keypad. But as soon as a music shortcut button is pressed, the surface morphs into five buttons for music navigation: play/pause, seek forward, seek backward, shuffle and repeat. Pressing another shortcut button to start the ROKR’s camera mode shows four buttons for zooming in or out, switching to playback mode or changing to video. Motorola (MOT) calls this its ModeShift technology. Though the lower half of the ROKR can be considered a touch device, objects can’t be manipulated with gestures like pinching or dragging as with the Apple (AAPL) iPhone’s multitouch screen.

Overall, I found that the ROKR E8’s dynamic keyboard gave me a real advantage in figuring out how to use the multi-functionality of the phone. Its changing keyboard eliminated a lot of guesswork and time that I may have spent hunting through menus for a command. And true to its name, the ROKR (pronounced “rocker”) is focused on its music phone functionality with an FM radio, a neatly organized music menu and a speaker that has convincingly simulated surround-sound effects.

But this ROKR didn’t always jam out in perfect pitch. A touch-sensitive semicircle in the center is meant to make scrolling through long lists easier — much like Apple Inc.’s iPod wheel. But because this tool on the ROKR isn’t a full circle, scrolling felt unsatisfying. You also can’t buy songs with the ROKR, or even mark songs for purchasing later on a PC.

And while the morphing buttons look futuristic and hip, I experienced a few instances when the phone was slow to react after I touched a button, as when I touched the seek forward button while listening to music or when I chose to open an MMS message I sent to a friend.

Twenty-two tiny bumps dot half of the ROKR’s surface, and the surface below each bump vibrates when it’s touched to provide sensory feedback. Nothing is ever physically pressed down, though the vibration response leads you to think otherwise.

A smart switch on the side can be held down to turn it on or off, or switched into the upward position to lock the device, preventing accidental calls or battery drain.

The ROKR E8 runs on T-Mobile’s (DT) GPRS/EDGE connection, which felt sluggish at times. And not even the dynamic keyboard on this device could help make email or instant messaging easier.

It has a two-megapixel still camera with an 8x digital zoom that can change into video-camera mode in one step. Two gigabytes of memory are built into the ROKR, and more memory can be added via a microSD card slot, which is hidden beneath a back panel. A one-gigabyte microSD card comes with the ROKR. Without this card, the internal memory will hold about 1,500 songs.

With help from a USB cord and Windows (MSFT) Media Player 11, I transferred over 200 MP3s onto my ROKR. Album art that transferred with my songs appeared on-screen as songs played, and the speaker gave off a powerful sound. Built-in stereo Bluetooth can send tunes to Bluetooth-enabled stereo speakers, and it took me just a few seconds to pair my ROKR with Motorola’s EQ5 speakers.

A preloaded program by Shazam lets users hold the ROKR up to any speaker playing a song, and in 30 seconds, identifies the track title, artist, and album art. I held the ROKR up to my alarm clock radio and it worked perfectly. But once these songs are recognized, the track data can’t be used to buy the song or even to transfer a request to buy that song to a PC for buying online at another time.

The ROKR’s FM radio will work only if its included stereo headset is plugged in because the headset has the radio antenna. But once the headset is plugged in, the radio will play via the ROKR’s speaker.

The ROKR E8 has an audio technology called Crystal Talk, which Motorola says allows your phone to perform better in loud environments. Even if the person on the other end of your phone is in a noisy place, the company says Crystal Talk will raise the volume to improve the call. I tested this by speaking to someone on the ROKR while turning a hairdryer on beside the phone. I then used a regular Razr cellphone. The person on the other end said that the ROKR sounded slightly, but noticeably, better.

Motorola’s ROKR E8 is a head-turning phone with many built-in advances that give it a smarter interface. One might wonder what other ModeShift functions the company will integrate into its devices in the future, such as a full QWERTY keyboard. The overall idea of a dynamic keyboard is a step ahead for small devices. It forces the phone to work more intuitively and improves navigation while looking stylishly sleek at the same time.

A fondness for TiVo has encouraged users to refer to it with designated nicknames and/or genders. A teacher friend of mine was recently asked by a student if her husband’s name was TiVo after the child heard her say she would have to tell TiVo about a new TV show. But like any old friend — or spouse — who has been around for a while, TiVo has a few tricks up its sleeve that might surprise longtime users and new owners alike. This column includes just a handful of those tricks and highlights some features that may make TiVo more useful. These tips are for everyday users, not serious hackers, and many others exist.

Remote-Control Codes

Each of these codes is entered one time to enable an otherwise-hidden function, and three chimes signal the code is set. These functions can be disabled by entering the code a second time, or if TiVo is rebooted.

Clock: If you miss having a VCR nearby to tell you the time while you watch TV, TiVo can help. A digital clock can be programmed to show up in the lower right-hand corner of your television screen by pressing “SELECT-PLAY-SELECT-9-SELECT.”

While playing recorded shows, this clock displays the current time and the elapsed time of the program you’re watching. Personally, I check a show’s progress by pressing the remote’s Play button to see the progress bar, and the Info button shows the current time. But the on-screen clock might come in handy when you’re watching TV on a terrible date and you don’t want to get caught glancing at your watch.

30-second skip: One of the glorious functions of TiVo and other DVRs is their ability to fast-forward through commercials. But it takes practice to know when to press Play so as to completely miss commercials.

If you’re unsure about your fast-forwarding technique, TiVo can be permanently set to skip ahead in 30-second increments, by entering “SELECT-PLAY-SELECT-3-0-SELECT.” This code must be set while watching a recorded show. After that, the 30-second skipping works whenever you press the “Skip To Tick” button, which looks like an arrow pointing right to a straight line.

TiVo says this code won’t work for longer time increments, like 90 seconds, and I tried using various increments, to no avail. Still, pressing this button about five or seven times in a row (depending on the show) gets you through commercials with less guesswork.

Disappearing progress bar: TiVo’s progress bar, which shows how far along a program has progressed in terms of the entire show’s duration, appears at various moments, such as when you first play a recorded show or unpause. This indicator lingers on the screen for just about three seconds, but if this seems too long, you can enter “SELECT-PLAY-SELECT-PAUSE-SELECT” to set the progress bar to disappear after less than a second.

I tried this setting on my TiVo, but one second showed only a quick blink of the progress bar, not enough time to see anything.

Number Shortcuts

From the TiVo Central menu, pressing each number on the remote control’s numeric keypad skips directly to a different tool. Some of the more useful shortcuts include pressing “1″ to go to Season Pass Manager (a list of programs that are set to automatically record every episode), “4″ to go to Search Title and “8″ to go to TiVo Suggestions.

Viewing Tips

TiVo can display a programming guide in a TV-Guide-like grid, or as a two-columned TiVo Live Guide that can list future shows for hours or days out. The top of Live Guide gives a detailed description of each selected program, along with its duration and TV rating.

The Now Playing list shows content stored on a TiVo. By default, this list is organized in time sequential order with same-series TV shows grouped into folders. Remote-control shortcuts re-sort this list: pressing “1″ switches from sequential to alphabetical order and vice versa; pressing “2″ ungroups shows to display each title; shows are regrouped into folders when “2″ is pressed again.

Lesser-Known Features

Universal Swivel Search is a way of seeing how TiVo’s various shows and movies are related to one another. It lists details about each program, including actors, directors, tags associated with a show (like love, dating and addiction) and suggestions of similar content. Swivel Search is accessed through the Find Programs menu or More Options while looking at a recorded show.

By selecting a Swivel Search detail about a particular show, such as one of its actors, you can see what else he or she starred in and whether or not that show or movie is available through TiVo or Amazon.com’s Unbox. Unbox downloads movies directly to your TiVo ranging from $2 to $15 each depending on whether you rent or buy a movie.

Plenty of free Internet content can be downloaded from the Web to your TiVo. But TiVo confusingly places this content in two menus: Find Programs and Music, Photos, Products & More. Under Find Programs, a Download TV & Movies section offers Amazon Unbox movies and free TiVoCast content. The latter can be set to automatically download with Season Pass settings, such as The Onion’s weekly video or ExerciseTV’s twice weekly videos.

The Music, Photos, Products & More menu holds content like photos and unprotected MP3s from a nearby computer, podcasts, Rhapsody music, Yahoo! Weather and Traffic and on-screen games. You can even buy movie tickets through Fandango.

TiVo takes up valuable space in a home entertainment center, so it’s important for the company to make sure its content is varied and useful. The codes and shortcuts mentioned can change the way you use this valuable device every day.

Digital Cameras

Megapixels: This term describes the highest resolution photo a camera can take. Often mistaken as the most important factor in a digital camera, a high megapixel count — such as 10MP or more — isn’t necessary for the average user unless he or she plans on heavily editing or enlarging photos. Most new digicams offer between five and eight megapixels, which is usually more than enough.

Optical or Digital Zoom: Optical zoom, determined by the physical movement of a lens, matters much more than digital zoom, which digitally alters an image using the camera’s internal computer. Camera companies still try to confuse potential buyers by listing a camera’s total zoom, or the optical and digital zooms multiplied together. Ignore total zoom numbers and instead focus on optical, which now averages around 5x for many new cameras.

Image Stabilization: When generously sized LCD viewing screens started replacing optical viewfinders, they also forced users to hold their cameras at arm’s length, making for plenty of blurry photographs. To remedy this, camera manufacturers have added image stabilization, tools once found only in high-end SLR models. Optical (also called “mechanical”) and digital image stabilization correct for unsteady hands and moving subjects, respectively. Cameras with both types advertise dual image stabilization, which corrects for both situations and costs more.

Mobile Devices

HSDPA and EVDO: HSDPA, or High Speed Downlink Packet Access, is the name for AT&T’s 3G, or third generation, mobile network that operates at roughly the speed of a slower DSL in a home. HSDPA is available in most major metropolitan areas and is seen as the competitor to Verizon and Sprint’s EVDO (Evolution Data Only) networks, though the popular iPhone runs on AT&T’s network using Wi-Fi and EDGE technology rather than HSDPA.

Multi-Touch Technology: Most popularly found on Apple’s iPhone and iPod touch, multi-touch is starting to show up in other products, such as in Microsoft’s Surface, a coffee-table-like computer. Rather than just responding to on-screen touches, this technology enables moving, resizing and zooming pictures and Web pages using one or more fingers simultaneously. Look for many more devices — mobile and otherwise — to incorporate multi-touch in the future.

GPS: Global Positioning Systems are most often found in cars — either built-in or on portable devices from companies like Garmin and TomTom. These gadgets use satellite technology to determine geographic location, and high-end models even display Web content like news and weather along with directions. GPS integration in mobile devices can be used to plot routes in cars, can help users find nearby businesses while on the go and can link friends by showing one where the other is located and what they’re doing.

Digital Music

DRM: Digital rights management is a set of standards that protect the intellectual property rights of online content like music and videos, preventing it from being illegally distributed across the Web. In the past year, Vivendi’s Universal Music Group, Apple and (most recently) Sony BMG said they will start selling DRM-free versions of songs, often for a higher price. In Apple’s iTunes store, these files are called “iTunes Plus” and aren’t restricted like other iTunes content.

MP3: MP3 files are open, without any DRM restrictions. Files that you rip (copy) from your own CDs are usually converted into MP3s, though iTunes users can automatically rip tracks into that program’s special format, called AAC. MP3 files can be uploaded to social-networking sites for sharing with friends and online communities.

These file types are protected by rights that tie them to specific players. Generally, AAC files make up the majority of tracks sold on Apple’s iTunes store and play only on Apple’s iPods; WMA files are Microsoft’s version of proprietary files.

Wi-Fi

The popularity of Wireless Fidelity, or Wi-Fi, brings this technology to more and more portable devices like the iPod Touch and Microsoft Zune and gives companies good reason to incorporate Wi-Fi receivers in new computers — laptops and desktops alike. While available in many flavors, different letters like b, g, a and n stand behind Wi-Fi’s more technical name, 802.11, to help discern one version from another according to characteristics like speed and compatibility. The latest version, “n,” offers the greatest range and speed, and “n” devices are usually compatible with earlier versions.

Televisions

HDTV: High-definition television has now become the standard, capable of displaying vastly better pictures, provided the source is also HD. Today’s more popular flat panel HD televisions are LCDs, or liquid crystal displays, though plasmas still hold their own. Recording HD content can’t be done with a regular digital video recorder; instead, a special HD recorder is required to capture this higher quality content.

480p vs. 1080i vs. 720p vs. 1080p: These numbers refer to the resolution, or sharpness, of a digital display, while “p” stands for progressive and “i” stands for interlaced. A resolution of 480p, known as EDTV or Enhanced Definition TV, is found most often in low-end plasmas or LCD screens. A TV with a resolution of 1080p is currently considered the Holy Grail, and costs the most. But 1080p pictures usually can’t be distinguished from less expensive 1080i or 720p pictures by average viewers at the typical distances from which most folks watch TV.

Blu-ray vs. HD DVD: Blu-ray and HD DVD are incompatible high-definition disc formats that continue to fight a seemingly endless battle to replace the DVD. The Blu-ray camp is led by Sony and the HD DVD camp is led by Toshiba. The two formats aren’t so different, technically speaking, but their very existence is confusing to consumers. The recent decision made by Time Warner’s Warner Bros. to use Blu-ray gives Sony’s side a boost, and now Viacom’s Paramount is rumored to be switching to Blu-ray from HD DVD. Dual-format players from Samsung and LG offer some solace.

This week, I dived into the music blogging world of MOG.com, a Web site where enthusiasts can read, blog and network with one another. Starting today, this site will integrate with Rhapsody, the subscription-based music service, so that MOG users, or MOGGERS, can simultaneously blog about and listen to millions of songs that fuel their online discussions.

Rhapsody is now integrated into MOG’s site for music aficionados.

MOG Inc. prides itself on working as a destination for people who hope to discuss music tastes and opinions, like TripAdvisor.com works for travelers. MOG’s first public beta, or test version, came out about a year and a half ago.

Its use of a subscription model comes at a time when CD profits are lagging and larger social-networking sites are negotiating with record labels to incorporate music streaming. Plenty of people still prefer purchasing music a la Apple Inc.’s iTunes Store, where there aren’t restrictions due to streaming or subscriptions.

Along with built-in Rhapsody, this newly enhanced version of MOG includes other improvements, such as a better search engine and a speedy tool that generates personal profiles for each MOG user according to his or her musical tastes.

I was granted early access to MOG’s revamped site and was most impressed by its fast search tool, which works just like the Spotlight search in Apple’s operating system. Results are narrowed with each typed letter and returned in neatly divided categories. Best of all, music results came back as fast as if they were on my hard drive instead of various MOG pages and Rhapsody’s database.

MOG also does a good job of marrying its contents with Rhapsody in a way that isn’t overly obvious; tiny Play icons beside song titles can be selected to start hearing a tune through the Rhapsody player, which hums along in the background, and similar icons add songs to playlists in one step.

But for a site that prides itself on appealing to music enthusiasts, I found certain genres much more represented than others. The rock music category, for example, had plenty of related posts and coinciding Rhapsody music, but the classical music section was almost nonexistent and country tunes were poorly represented. I typed “Bach” into the search box, expecting to be flooded with results, but saw no music and only one post by a MOG user about why she thought Bach was a great composer. The company says it will fix this in the next couple of months.

Unlimited Rhapsody access costs $13 monthly and is offered free for the first 14 days. But, like all subscription models, it blocks access to music if you don’t pay this monthly fee. MOGGERS who don’t want to pay or don’t plan on using Rhapsody as much can choose from two free options: one that allows users to listen to 25 songs a month and another that only allows free 30-second clips of song.

MOGGERS can upload their own MP3s within blog posts on the site. But linking to Rhapsody songs was easier and faster.

I got started by clicking a giant “Magic Button” icon on the MOG site. This installed MOG-O-MATIC, a tool that automatically searched my computer’s hard drive for all of my music files, then indexed them and created a profile of my music taste on a personalized My MOG page. This tool was also available in the first version of MOG but is 10 times as fast now, indexing 10,000 songs an hour compared with 1,000 songs previously.

I liked that MOG-O-MATIC did some page-creation work for me, making a list of the songs I listened to most recently — regardless of what program I used to listen to the song (iTunes, Windows Media Player or Rhapsody). Another list that was automatically generated from my music showed which artist was best represented in my collection. If you don’t want the world to know about your Barry Manilow obsession, this list can be altered to fudge the truth.

Because MOG-O-MATIC scans your entire music collection, it knows what music you like. A Recommendations page shows you what other MOGGERS with similar tastes are listening to, helping you discover new tunes. I found these suggestions to be pretty accurate, and even discovered a great song on another MOGGER’s recommended playlist called “Summer Teeth” by Wilco. I checked out the page belonging to the MOGGER who created this playlist, and found other tunes that were in line with my musical taste.

Using Rhapsody, I played entire Web pages of recommended songs with one click. Likewise, entire music collections belonging to other people can be played the same way, as long as you have the right Rhapsody account to play that many songs.

I wrote a blog post on MOG about the newest album from “Fountains of Wayne,” and it automatically included a Play button icon, enabling the song I wrote about to play along with my post. This auto-linking is done with fill-in-the-blank boxes that tag each post with music.

MOG isn’t trying to be a social-networking site that enables all things. Instead, it focuses on one thing, music, and successfully improves the way people discuss, share and discover music online.

Tubes installs a program on the desktop (right) into which files can be dragged and shared using automatic synchronization.

This week, I tested another product in the long line of programs that uses automatic synchronization to simplify the process of sharing large files by giving you the ability to change files and privacy options at any time. It’s called Tubes (www.tubesnow.com) from Tubes Networks and it takes its name from the pneumatic vacuum-tube system commonly used in bank drive-throughs that motivated me to join my Mom on visits to the bank as a kid. Mom would pull up and a container would whoosh over through a tube to arrive beside the car window; after a quick exchange it returned with her deposit slip and a lollipop for me.

Tubes aims to work with the same sort of magic. Once installed, its desktop application stays opened on your computer as a place where “tubes” are made for sending files. Any type of file can be dragged, dropped and sent off to share with other people using these virtual tubes. As soon as you release data into a tube, a whoosh sounds (like that of the vacuum tube) and your files are encrypted and uploaded to the Tubes server.

Invited guests view your tube’s data in its full, uncompressed format. The owner of the tube always has the final say on what is shared with whom, and changes made to tubes on your hard drive are detected instantly via automatic synchronization, guaranteeing viewers will always see the latest version of the tube. Shared tubes are also accessible via the Web, saving viewers from downloading the Tubes desktop program.

Other products like Sharpcast (www.sharpcast.com) and Pando (www.pando.com) also offer ways to share large digital files; Sharpcast uses synchronization similar to that of Tubes — it all happens behind the scenes without any work on the user’s part.

Tubes is available in a free version that provides a gigabyte of storage, or in paid versions with five, 10 and 20 gigabytes of storage for $6, $11 or $21, respectively.

Most of the time, Tubes worked well for me when I installed it on two Windows machines, one running XP and one running Vista. Tubes’ smart use of an already familiar process — dragging and dropping — gives you the impression that you already know how to use it and makes sharing files seem easy. I started dragging all sorts of files into tubes that I created, naming them and labeling them with a representative icon (one of 10 offered by Tubes or one of my own images).

For all its usefulness, Tubes certainly has room for improvement. For now, there isn’t a Mac version of the program, and when friends and I tried accessing shared tubes using a Mac Web browser, the results were inconsistent and sometimes didn’t work at all. Windows Vista had its own issues. After installing Tubes on my Vista laptop, an error message labeled “invalid argument” made me feel like a member of the debate team. And I couldn’t see thumbnail images of photos in my tubes using Vista, though I could on Windows XP.

Today, Tubes is releasing an updated version of its program that aims to improve the usability and look of the product, including refining the processes of sharing tubes and looking at tubes via the Web.

Before sharing tubes, I adjusted the permissions granted to each guest by labeling them as a Reader, Author or Editor; only the Owner can invite others to view a tube. But these labels can get confusing. More than once, I granted guests the highest level of permission, which is Editor, allowing them to make changes to the files in my tube, only for the guest to be asked for his registered Tubes email and password, which an invited guest shouldn’t need.

The Tubes experience was best when the recipient of my Tubes invitations had the application installed on his or her desktop.

After installing Tubes on a computer at work, I installed it on my home PC and easily auto-synched tubes that I created at work onto my home PC — a big plus.

Tubes incorporates the Web by assigning a unique URL to every file in every tube, and every tube automatically generates its own Web site, or “tubeSite,” as it’s called. Individual URLs for each file can be found by right clicking on a file and selecting an option to copy the URL into an email or browser. I copied the URL of a shared MP3 audio file and pasted it into my browser; it played a Fountains of Wayne song with no problem. But sharing these URLs with others is only possible if the owner gives permission.

Comments about tubes can be made in the “tubeBlog” — accessible through any tube in the application or online. I created a tubeBlog for a tube with photos from one of my vacations, adding descriptions and comments to specific photos. Others, with my permission, could do the same, using the photos from the tube or just leaving comments.

A friend used Tubes to share photos with me while vacationing in Italy and Amsterdam. I added my own travel photos and an itinerary made in Microsoft Word to his tube and changed the tube’s title; these alterations synched instantly.

Even if you aren’t online, you can access tubes or make changes to them by dragging files in or taking them out; updates are made automatically the next time your computer connects to the Web.

Tubes is off to a good start, but it needs to improve its system to make permission levels more understandable for tube owners and those invited to see a shared tube. With a few improvements, Tubes could be a product that I’ll continue using on Windows computers long after this column.

If our email from readers is any indication, baby boomers are bugged by a persistent problem: They need a simple way to convert all those vinyl records they’ve been accumulating since the 1960s into digital song files, or at least CDs.

So, this week, we sat down with two devices that are designed to bring new life to the old 45s and LPs that boomers cherish, allowing those oldies to migrate to CD players, computers and iPods.

One device, the $400 LP-to-CD Recorder Stereo System by Teac America Inc., serves as an all-in-one stereo and CD burner. It’s a standalone unit that doesn’t connect to a PC. The other device, the $200 Ion USB Turntable (iTTUSB) by Ion Audio, is a turntable that plugs directly into your computer via an attached USB cable.

Ion USB Turntable by Ion Audio, $199

The sight of a record player set up in our office stopped more than one nostalgic passerby in his tracks, as did the sound of Bob Dylan’s “Like a Rolling Stone” blaring out from a crackling, fuzzy record.

While the iTTUSB sounds like it might offer a more direct method, its included music-transfer software program is way too confusing and technical for average users, and would make sense only to an audiophile or techie. It also doesn’t automatically detect where tracks on records start and end, forcing users to manually separate each new track. So we simply can’t recommend it for average, mainstream users.

The Teac LP-to-CD Recorder Stereo System gets our vote, thanks to an easy set-up process and better overall usability, even though it only creates a CD, not music files on your PC. It requires an extra step to do that. But it does have an automatic track-detection feature.

We would have liked it if at least one of these devices automatically edited tracks, cleaning up record hisses and pops.

Walt headed to a local record store to buy some old favorites for testing, as his vinyl collection was finally discarded in a recent home renovation. Armed with 45s and LPs by Bob Dylan, the Beach Boys, Elvis, the Beatles and Barbra Streisand, we got started with the all-in-one solution — the Teac LP-to-CD Recorder Stereo System, available from Hammacher Schlemmer. This works independent of your computer — making it more universal and less intimidating for some, compared with the Ion USB Turntable, which must plug into a computer to work.

This device is sturdy and handsome, encased in a black wood frame with a lid that opens to reveal the turntable. Its front side is more modern, with a series of circular silver buttons, a CD drawer and a digital display book-ended by built-in speakers. Aside from copying your vinyl music onto CDs, this unit also plays CDs, records (45s and LPs) and has a radio.

LP-to-CD Recorder Stereo System by Teac America, Inc., $399.95

Even better, unlike the Ion, it has a feature that will automatically detect the start and end of tracks, although it may not work well with some records, due to background noises like scratches.

This LP-to-CD Recorder burns only onto special CD-R or CD-RW discs that have “Digital Audio” labels and are less common than other recordable CDs used for burning mix CDs on computers.

We inserted one of these CD-Rs into the player and placed “Bob Dylan’s Greatest Hits” onto the turntable, turning on Phono mode. We pressed Record, swung the turntable’s arm over onto the outer edge of Side A and pressed Play. The digital display showed track one and counted up from zero to mark elapsed time.

To mark the start of a new track, you can adjust a setting to automatically do so, but in our tests, auto detect was unreliable. If you don’t choose this option, you must press a button called “Track Increment” on the player or its remote. But this option is easier said than done, especially while listening to old favorites. We caught ourselves harmonizing along to “I Want to Hold Your Hand” by the Beatles, forgetting our CD-making duties at the end and quickly scrambling for the remote.

After one side was finished, we paused recording to flip the record and pressed Pause again to resume. When the turntable ceased rotating, recording automatically stopped. To make a CD playable on other devices and computers, we pressed Finalize; about a minute later, the CD was done. We finished converting “Bob Dylan’s Greatest Hits” in 45 minutes. Our test CDs sounded good, but the Teac unit has no ability to clean up any scratches, pops or hisses that may afflict your old records.

After we burned our test CDs, we were able to insert them into a Windows or Macintosh computer and import the tracks as MP3 files.

Using the Ion USB Turntable, or iTTUSB as it is called on the box, was a more frustrating and laborious process, thanks to its assembly-required turntable and its geeky file-converting software program, Audacity.

The iTTUSB itself is simple-looking, and it should be; it is being sold at places where mainstream users shop, such as J.C. Penney, Circuit City and Urban Outfitters. This plastic, gray turntable comes disassembled, and Katie followed steps for setting up the platter and balancing the tone arm’s counterpoint device. But this process wasn’t nearly as complicated as using the Audacity software program.

Audacity opened and worked — but only after we followed the manual’s exhausting instructions and got help from the company’s tech support. One step had us searching a list of confusing terms to select our computer’s sound card, a task that would rightfully baffle any mainstream user. We listened to tracks through our computer’s speakers as we copied music onto our computer.

But Audacity’s most glaring problem is its inability out of the box to convert your imported vinyl tracks into MP3s — the main purpose of the product. To do this, you must leave the software program, go to Audacity’s Web site, find the URL link for a third party’s Web site, download an MP3 conversion plug-in and run it within Audacity. The software never explicitly tells you how to do this.

We followed these steps, and it took us about 10 minutes to walk through the process of converting our first track into MP3 format. Most users would never get this far, with good reason. They wouldn’t even understand the instructions.

The Ion/Audacity combo requires you to manually mark the start and stop of a track, so transfers can’t be unattended. If you so choose, you can manually go through each track to edit out the extra noises heard on records, but we can only imagine how time-consuming this process might be.

Next April, Ion Audio plans to introduce its own software program that will come bundled with the iTTUSB. Ion says this will have its own built-in MP3 conversion program, as well as the ability to automatically detect the start of new tracks.

We found Teac’s LP-to-CD Recording Stereo System to be a good, if imperfect, solution to the vinyl-to-digital quandary. It will take time to work through all of these conversions, but after you’re done, your music will be unleashed.

Over 50 million Apple iPods, and lots of competing digital music players, have been sold by now — as well as over a billion songs and tens of millions of videos, since legal media sales took off a few years ago.

But many folks — even some who own iPods and other players — are still confused over how legal digital music works. So here’s a quick-and-dirty guide to the digital music world, in question-and-answer form. We’ve included the questions we are asked most frequently, plus a few other topics.

What’s the difference between the Apple iPod and all the other portable music players? Some of them seem to have more features.

The main difference is that Apple has created an entire end-to-end digital media system around the iPod, and it works. In our view, and those of most other reviewers, the combination of the iPod’s design, the iTunes music software, and the iTunes Music Store, provides a superior experience to buying a player separately, using software from Microsoft, and buying music from an unaffiliated store.

As a result, the iPod, and the iTunes store, dominate the legal music world, with shares of more than 70% of the market, depending on how you measure it.

Still, players from companies like iRiver and Creative are attractive and have some features the iPod lacks, such as built-in FM radios. And music services from RealNetworks, Yahoo, Napster and others offer an interesting alternative to iTunes.

If I buy an iPod, must I buy music from Apple’s iTunes store? Conversely, can I buy music from Apple, and play it, if I don’t have an iPod?

No, and yes. You don’t have to buy a single song from Apple. You can fill an iPod entirely with music you convert from your own CDs, or which you get from unauthorized download services, or from friends. The latter two sources are probably illegal, but they are technically easy to use. In fact, most of the song files on most of the world’s iPods weren’t purchased from Apple, or anyone else. That’s because the iPod, and iTunes, can play back files in the open MP3 format, and in other non-copy-protected formats.

Conversely, you can set up an account with the iTunes Music Store and buy as many songs, videos, and other material as you like, without owning an iPod. You would simply play back your purchased media on Windows or Macintosh computers. You can play any one song on as many as five different computers. All you need is the free iTunes software, which can be downloaded from Apple’s Web site in either a Windows or Mac version.

Will songs purchased from iTunes play back on non-iPod portable players? Will songs purchased from competing services play back on iPods?

No, and no — unless you use a workaround (see next answer). At the insistence of the record labels, all songs from major label catalogs that are sold as online downloads must be encrypted to limit copying. There are two encryption formats. One is owned by Apple, and the other is owned by Microsoft. The iTunes Store uses the Apple encryption format, and most other legal download services use the Microsoft format.

Any player from any company can theoretically be enabled to use either format, but Apple refuses to license its encryption format to any competing maker of players. And Apple also refuses to incorporate the Microsoft format on iPods. The result is that songs bought from iTunes only work on iPods, while songs bought from most other legal services only work on non-iPod players.

There is one exception. A service called eMusic sells its songs in the open MP3 format, without encryption or copy-protection. Thus, these songs will play on iPods and all other portable music players. But eMusic doesn’t carry the catalogs of the major labels. It has a much smaller selection than iTunes does.

Is there any way around this? Can I legally modify or convert encrypted songs so they will work on portable players for which they weren’t intended?

Yes, but the method is clumsy, especially if you try to apply it to a large number of converted songs.

To convert songs purchased from iTunes to an open format that will play on, say, a Creative player, or in Windows Media Player software, you first must burn the songs to CD. Then, using iTunes or other music software, you re-import them from CD, turning them into open MP3 files that can be played on any player. This works fine, but it has two big downsides.

First, it can take a long time to convert, say, 500 songs this way. Second, the process strips off all the identifying data from the song files, and home-burned CDs typically aren’t recognized by the automatic song-recognition process used by iTunes and other software. So you’ll have to manually re-enter info like artist, album and song title.

Independent site iLounge has a free manual on getting the most from your iPod.

This process works the other way as well, with a big “if.” You can convert Microsoft-encrypted songs this same way, so they become MP3 files that can be played on an iPod. But the catch is that songs offered by the leading Microsoft-based services often can’t be burned to CDs. (See next answer.)

There is some software that claims to efficiently strip the encryption from copy-protected song files, turning them into MP3 files. But these programs are almost certainly illegal under recent copyright laws, and Apple and other companies constantly change the innards of their encryption formats to foil the programs.

What is the difference between Apple’s iTunes store, and competing services like Rhapsody and Napster 2.0? Does one carry more music?

Apple’s iTunes store claims to have more than three million songs licensed from the major labels and from independents. Rhapsody and Napster claim more than two million songs, and Yahoo Music Unlimited claims more than one million. So, iTunes has by far the most music. In addition, iTunes has a strong selection of videos, including 150 television series, plus tens of thousands of audio books and podcasts. Its competitors are much weaker in these non-music categories. Most have nothing at all besides music.

The main difference lies in how the services work. iTunes works like a physical record store: you buy songs or albums, paying separately for each. Songs are 99 cents each, albums are usually $9.99, and videos are typically $1.99. Apple is reportedly negotiating to sell full-length movies as well.

Rhapsody, Napster and Yahoo work on a subscription model: you pay a monthly fee, and can download an unlimited number of songs. For Rhapsody and Napster, the fee is $10 a month if you want only to store and play music on a computer, or $15 a month if you also want to play your music on a portable player. Yahoo charges less — $6.99 a month for a PC-only plan and $11.99 a month for a portable plan.

The upside of Apple’s approach is that, once you buy a song, you own it. It never expires. You can burn it to CD an unlimited number of times, and transfer it to an unlimited number of iPods. The downside is that, to fill an iPod with, say, 5,000 purchased songs, you’d have to spend $5,000.

With the subscription plans, you can fill a portable player for just a monthly fee. But there’s a huge downside: you don’t own the music, you merely rent it. If you stop making your monthly payments, all the songs you downloaded over the years will suddenly expire and become inert and unplayable on your computer and on your portable player. Also, rental songs usually can’t be burned to CD and can only be copied to a limited number of portable players. In order to burn the tunes to CD, you generally must first buy them for an individual price, just as you do on iTunes.

How do I use multiple iPods with one iTunes library on my PC, if I want different music on each iPod?

In the Preferences section of iTunes, you can set up each iPod so it synchronizes only with particular playlists, not your whole library. Just set up a playlist for each iPod, and set it up to sync only with that playlist.

Or, you can set up each iPod so it doesn’t automatically synchronize with iTunes at all, and simply works in manual mode. Then, you can manually drag different songs into each iPod.

Can I copy the songs on my iPod to my second or third computer?

At the insistence of the record labels, Apple was forced to cripple the iPod so it can’t copy music to a computer, out of the box. Copying only works from a computer to an iPod, not the other way. But there are many third-party utility programs, for both Windows and Mac, that allow copying from an iPod to a computer. One example is PodUtil, which has versions for both Mac and Windows. It’s at: www.kennettnet.co.uk/software/podutil.php.

One thing to bear in mind: you can only play any song you buy from iTunes on up to five computers, Windows or Mac. Songs in the open MP3 format can be played on an unlimited number of computers.

Can I share the music in my iTunes software with others?

Yes, within limits. You can set up iTunes on your Windows PC or Mac so that others on your computer network (but not over the Internet) can stream, or listen to, your songs, without actually moving the song file to their computer. The receiving computer must have iTunes installed, and both machines must be enabled for sharing in the Sharing section of the iTunes Preferences panel.

What can I do with an iPod, other than play music on it?

Current iPods can play videos, like TV shows. And most iPods can play audio books and podcasts. Recent models also can play back your photos as slide shows, accompanied by music and fancy transitions. And, with a $20 cable, the iPod can display videos and photos on a TV set.

But there’s a lot of other stuff buried in an iPod. The iPod can display, but not edit, your calendar and contacts and notes, synchronized from your computer. This works with Microsoft Outlook on Windows and with the Address Book and Calendar programs that come with every Mac. Current iPods also have a built-in stop watch and multi-city clock.

You can also use your iPod as a portable hard disk. It can be set up to appear as a regular hard disk on both Windows and Macintosh computers. Any space on the iPod that isn’t occupied by your music, videos, photos and so forth can be used to store any type of file you want, for backup, or for transfer among computers. You just have to plug your iPod into your computer, go to the iPod preferences tab, and check “Enable Disk Use.”

The iPod also has some built-in games. My favorite, Music Quiz, tests your knowledge of your own music. It plays a short clip of a randomly selected song from your collection, then displays five multiple-choice song titles. Your task is to select the right title in the shortest possible time, while a clock counts down the points you can win. It’s addictive.

There’s a ton more to know about digital music, and specifically, iPods. Apple has a series of iPod and iTunes tutorials at http://www.apple.com/support/ipod101/. The independent Web site iLounge (ilounge.com) is packed with tips and tutorials and even offers a free, downloadable 194-page book about the iPod, at: http://www.ilounge.com/index.php/news/comments/download-now-the-free-ipod-book-20.

How do you dislodge Apple’s mighty iPod music player, and its popular iTunes music service, from their total dominance in the digital-music market? Numerous hardware companies and music services — most backed by Apple’s historic rival, Microsoft — have tried, and failed, with all sorts of approaches.

Some contenders were cheaper. Others had built-in features the iPod lacked, like FM radios. Some had more capacity, or greater battery life. Others relied on monthly subscriptions instead of per-song fees. But the public has mainly yawned, and none of these approaches has gained any traction.

Today, a small New York City company called MusicGremlin Inc. is rolling out a fresh approach to denting the iPod hegemony: the wireless music player. Its new $299 Gremlin portable player has built-in Wi-Fi wireless networking, so it can download songs from an accompanying subscription service directly, without requiring the use of a personal computer.

Not only that, but Gremlin users can wirelessly exchange entire songs right from their players, legally, as long as both the sender and receiver are subscribers to the MusicGremlin Direct service, which costs $14.99 a month. This process, called “beaming,” allows you to share songs with your Gremlin-toting pals, no matter where they are, without ever using a computer or a CD burner. You can even peer into other users’ Gremlins to see what they’re playing and what they’ve downloaded, and pluck any song you like from their devices, if they give you permission.

The Gremlin is available today at Amazon.com, and the company’s own Web site, musicgremlin.com. While it doesn’t require a computer, the Gremlin can synchronize with a PC, but this only works with Windows machines. Its Web site requires Microsoft’s Internet Explorer browser and Windows Media Player for full functionality. The subscription service, which is optional, is free for the first month and offers unlimited downloads from a catalog of two million songs, about the same size as Apple Computer’s catalog.

We’ve been testing the Gremlin player and the MusicGremlin service, and we like them. The experience of downloading new music from the palm of your hand and sharing it legally with others is refreshing and fun, and can’t be done on our trusty iPods. Plus, MusicGremlin is one of the few iPod competitors we’ve encountered that shares Apple’s strong dedication to a smooth, end-to-end experience, where the hardware, software and online service work seamlessly.

However, this first version of the Gremlin has some major rough spots, in its user interface and in its wireless behavior, that detract from the experience and can get downright annoying. The company promises to fix these, but some other limitations can’t be repaired as easily. For instance, the magic doesn’t work if you aren’t in range of a Wi-Fi network you can use. And limitations imposed on MusicGremlin by the record labels mean that you can’t share certain kinds of songs, including legally obtained MP3 files that you transfer to the Gremlin from your computer.

Also, for $299, the Gremlin holds far less music than the $299 base model of the full-size iPod — just eight gigabytes, or 2,000 songs, versus 30 gigabytes, or 7,500 songs, for the $299 iPod.

The Gremlin player is a rather plain, black, chunky-looking device with none of the visual sex appeal of the iPod. It’s the same width as the base $299 model of the full-size iPod, but slightly shorter and thicker, at 0.76 inches, versus 0.43 inches for the iPod. At four ounces, it’s lighter than the iPod (which weighs 4.8 ounces).

The Gremlin’s color screen is smaller than the iPod’s — two inches, versus Apple’s 2.5 inches. And, instead of Apple’s excellent scroll wheel, the Gremlin uses a clumsier five-way navigation pad, like the ones on some cellphones. The Gremlin’s volume and playback controls are on its side. Battery life is 10 hours, versus 14 hours for the similar-size iPod.

Unlike the iPod, the Gremlin can’t display photos or videos. It can technically play back podcasts or audiobooks, but no podcasts and only a few audiobooks are yet available on the MusicGremlin service. It does include an FM radio, which the iPod lacks.

In our tests, the wireless features worked well — when we were able to get wireless connectivity. We could pick from the service’s huge catalog and download songs at will. The device shows you how many songs are queued up for downloading and reports on its progress in fetching them. If you lose the Wi-Fi connection, the process pauses and resumes later when you’re connected again.

We were also able to send and receive songs via beaming. We saw a list of other users and could easily send them songs and receive beams, giving permission each time.

But the Gremlin often told us it couldn’t find a wireless network, even when we were just a few feet from a Wi-Fi base station that laptops in the room located easily. And, in order to save battery power, the Wi-Fi feature shuts itself off frequently. It can be slow to come back and sometimes doesn’t come back at all.

On one occasion, when we were sitting next to each other with our test Gremlins, the devices couldn’t see each other, because the Wi-Fi on one or the other device had turned off automatically and wasn’t coming back up.

A last-minute software upgrade yesterday improved some of this wireless behavior, but the company acknowledges that more work is needed. (The device can be quickly upgraded by the company with bug fixes and new features, over the wireless network.)

The Gremlin won’t work with some commercial Wi-Fi hot spots, which require a Web browser to connect. But it comes with the built-in ability to connect to T-Mobile’s large network of Wi-Fi hot spots, if you have a T-Mobile account and enter your account information into the Gremlin.

The user interface is much clumsier than an iPod’s. This is partly because there are more functions, like downloading, and the community-sharing capabilities. But some things aren’t well thought out. For instance, it’s not obvious how you get the song-playing display, which shows the album cover, to stay on-screen for more than a few seconds.

To pick a song out of a list, you have to laboriously enter letters of the alphabet using the down arrow, and many functions require lots of arrow clicks and navigating fly-out submenus. Again, the company promises to improve some of this navigation.

We easily synchronized music from our computers to the Gremlin, using a Windows PC and Windows Media Player. You can also view the Gremlin as an added disk on your Windows PC and just drag and drop files between the Gremlin and your hard disk. Only the latter method allows you to copy subscription songs from the Gremlin to the PC.

One really cool feature is the MusicGremlin Web site, which not only allows downloading of songs to either a Gremlin player or a PC, but automatically displays a list of all the subscription songs on your Gremlin.

Both the Web site, and the Gremlin itself, offer you the option of purchasing songs outright, for 99 cents each, just as on Apple’s iTunes service. Unlike the subscription downloads, these songs don’t expire if you end your subscription.

In fact, you could buy a Gremlin and decline to join the MusicGremlin Direct subscription service, just filling your Gremlin with purchased tunes or songs transferred from your PC. But you’d lose the community feature of the Gremlin, because only subscription songs can be shared.

Despite its drawbacks, the MusicGremlin player and service are a great idea done pretty well. There’s nothing else like them in the marketplace, and they represent a fresh approach to challenging the iPod. For some people, a system that cuts out the need for a PC and allows legal sharing of songs may just be the perfect iPod alternative. But the company will have to file off the Gremlin’s rough edges if it’s to succeed.

Great songs, like chocolate-covered strawberries, can be sampled once and adored immediately. This is good news for online digital-music stores, where anyone with an Internet connection and a buck can log on from a computer and download a new favorite tune seconds after hearing it.

Now, XM Satellite Radio Holdings Inc. is making this audio gratification even more instant. Last month, it introduced the first portable combination XM radio/MP3 player, the $400 Pioneer Inno XM2go. Anyone with this device who likes a song playing on XM can simply press a button and record the entire song onto the player. No computer is required, but you do need an XM subscription, which costs $13 a month.

The $399.99 Pioneer Inno XM2go combines portable satellite radio with a digital music player, but watch out for reception problems.

These recorded songs can’t be transferred to PCs or other players. But they can be bookmarked for purchasing online at Napster’s music store the next time the Inno is plugged into a Windows computer. This purchased version of the song can be used on computers and other devices (but not the Apple Computer Inc. iPod).

The new XM device, made by Pioneer Corp.’s Pioneer Electronics (USA) Inc., uses flash memory rather than a hard disk, and can store 50 hours of recorded XM Satellite Radio, plus about 8 hours or 150 digital songs copied from a computer. One half of the player is reserved for XM recordings, while the other half is reserved for MP3 or WMA music files. You can switch between the two modes by pressing a button.

The Inno is at the center of a lawsuit filed yesterday by members of the Recording Industry Association of America, who are challenging the legality of the device’s recording feature.

This week, we tested the portable Inno all around town. We liked the device itself, and enjoyed listening to various satellite radio stations on the go. But we were deeply disappointed with its radio reception, which failed in too many places. And we really didn’t like working with the Napster software when we synched the player with our PC. It was a hassle.

Our verdict: adding live satellite radio and the ability to record it onto a device is a good idea, and may appeal strongly to satellite radio lovers willing to pay $13 a month to subscribe. But, for people who just like music, the radio and recording features didn’t seem like reason enough for us to want to buy the Inno over, say, an iPod — especially given the downsides we encountered.

We liked the overall feel of the Inno, and it wasn’t too tough to get the hang of its buttons and functions. It measures 3.7 inches by 2.2 inches by 0.6 inches — just slightly smaller, overall, than a full-size iPod and a little bit thicker — and its 4.5-ounce weight makes it a tad lighter than a 30-gigabyte iPod. A 1.7-inch color screen on the front doesn’t take up the entire surface, and compared to an iPod’s 2.5-inch color screen, its size was more like the one on the tiny iPod Nano, a 1.5-incher.

The back and front sides of the Inno are decorated in cool gun-metal gray. Shiny black edges give it a modern feel, while its stubby antenna resembles that of a smart phone, but thicker and perfectly cylindrical. This antenna is the device’s only means of receiving radio. That’s a breakthrough, since satellite radio usually requires a large separate antenna or a car antenna. Unfortunately, we found the Inno’s little antenna was too weak.

It’s hard to overstate the reception problems that plague the Inno. We lost reception while driving through a short tunnel, walking through a row home and wandering through our office, away from the window. Even in an office with an entire wall of windows, we had to sit right next to the glass to get XM Satellite Radio reception.

Walking around downtown Washington, just a few blocks from the White House and a few miles from XM’s headquarters, the Inno constantly dropped the XM signal, even though Washington, by law, has no office buildings taller than about 12 stories. Walking just a few feet into a Starbucks killed the signal altogether. When we sat down on a bench in a small park, the reception got much better, but still wasn’t perfect. For a device that’s primarily a radio, this is a killer flaw. Of course, you can listen to the Inno’s stash of recorded music during these signal dropouts, but, when the failures are as frequent as ours were, this need to keep switching modes turns a supposedly pleasurable experience into a huge annoyance.

Optional headphones with an antenna disguised in the headpiece can be purchased for an additional $40, and these added slightly better reception, but not much.

A well-designed button on the right side of the Inno powers it on or off when pushed downward, and puts the device on hold when pushed up. Volume controls are just below this button, also on the device’s side. Three buttons line the bottom edge of the color screen — Mode, Play/Pause and Display — and four directional arrows surround an XM select button below these three.

We checked out XM’s 20 categories of music, over 170 stations altogether, by pressing the right arrow button. We paused in the Decades category to listen to “Sunshine Superman” by Donovan on the ’60s station before skipping to Hits where Daniel Powter’s catchy new pop song “Bad Day” was playing on the “Top 20 on 20″ station.

To record “Bad Day” onto our Inno, we pressed the XM button, chose Record and Record Song. A red “REC” icon appeared at the top of the screen, and went away when the song ended. In one case, we were listening to a station when a new song that we wanted to record started before we could press the right buttons. Thanks to the magic of satellite radio, recording automatically started at the song’s beginning, rather than halfway through.

If you’d like, you can schedule times for your Inno to start and stop recording, and these can be set to record on the current day, every day or on a specified date.

When listening to Elton John’s “Something About the Way You Look Tonight” on a romantic music station appropriately named “The Heart,” we opted to Bookmark the song so that it was set aside in a special category of songs for buying when we connected our Inno to our PC. An option called TuneSelect can be chosen while a song or artist is playing; from then on, a message will flash across your screen whenever that artist or song plays anywhere on XM, so you can tune in.

Before synching our Inno with our computer, we used an included CD to load XM + Napster software onto our Dell PC and typed in a special promotional code given to us by Napster for testing.

The Napster software program is confusing, to say the least. Napster offers three types of accounts: Napster Lite, music-store usage with no monthly fee that allows online listening and purchasing of songs à la carte; Napster Membership, a $9.95-a-month program allowing unlimited music downloads onto the PC — but not for transferring to a player; and Napster To Go, a $14.95 monthly membership that allows unlimited music downloading and transferring to a device.

If that doesn’t confuse you, add the fact that because Napster offers music rentals rather than just buying of songs — like iTunes — it considers purchased tracks to be different than downloaded tracks. Overall, your purchased tracks or previously owned tracks (in MP3 or WMA file format) can be transferred to the XM2go. Downloaded (not purchased) tracks can’t be transferred to the XM2go, but they can be transferred to special, more advanced devices with what’s known in techie land as DRM 10 compliance. XM plans to introduce devices with this technology in the future.

The Inno connects to a PC using a standard USB cable, but it must be simultaneously lying in its special sideways dock, which also powers the device. When the Inno is turned sideways in its cradle, its screen automatically rotates, as do its directional arrows. This cradle also has plugs for an additional included antenna and a line out, for using the Inno with a stereo system.

In Napster’s software program, our Inno was identified, as were the songs that we had recorded and bookmarked. Songs recorded from XM can’t be exported from the player, due to copyright laws. Most of the songs we had bookmarked, including Elton John’s tune, had a Download icon next to their track titles.

But instead of seeing a Buy icon next to our bookmarked tunes, we could only purchase songs by right-clicking on tracks and choosing Buy Track since our account type was designed for streaming music rather than buying it. This type of navigational confusion was abundant in the program, and users would easily and understandably be befuddled by what account type they had and what was or wasn’t included in it.

We dragged and dropped songs onto our Inno player without a problem, and they showed up in the MP3 section of the player when we started it up again. We even created playlists, right on the Inno, combining music recorded from XM stations and our own MP3s. Switching between the live XM stations and our MP3s and WMAs was easily done with the Mode button. XM estimates that the Inno’s battery will last for 15 hours in playback mode and five and a half hours in Live XM Mode.

When it’s all said and done, XM’s Inno is fun to use on the go, as long as you’re not underground or in room without windows. But its spotty reception, confusing software and monthly fee make the Inno a no-go, except for hard-core XM fans.
