This week, I tested Trulia.com, a real-estate site that’s geared toward helping people who are ready to buy. Trulia combines a simple approach to real estate that anyone can grasp, with enough market stats to excite number-crunching types. It also offers a community where regular users can ask 200,000 real-estate professionals questions without fear of being hounded by agents because their emails are hidden.

An iPhone app from Trulia.com uses GPS to find nearby open houses.

Trulia has been around since 2005, but started out as a site that only posted local real-estate listings in California and New York. After expanding to the national market in 2006, it added other features like pricing heat maps (color-coded to indicate prices in an area), comparable listings, an online community and automatically generated newsfeeds about specific properties and areas. Last summer, Trulia went mobile with a free iPhone app that uses GPS to find nearby open houses.

Starting Wednesday, Trulia will offer CompareIt, a tool that lets users choose five properties for sale to directly compare with one another. Before now, Trulia just generated a list of comparable properties that sold or are for sale at the bottom of a listing.

I only used Trulia for a week, and I’m not a typical buyer since I was just looking — for now. But I got a lot out of the site, especially by browsing maps of neighborhoods that I know well (I’m picky about my preferred location) and asking questions of the Trulia community. Its iPhone app listed nearby open houses according to my search criteria and also worked on my iPod touch as long as I was in a Wi-Fi zone.

Another big plus to Trulia is Newsfeed, a list that shows up on the home page with content that’s automatically generated and personalized according to your past search locations. It is updated every day and spits out stats like the number of price reductions, open houses and new listings in an area. It shows an area’s average listing price, median sales price, number of foreclosures and average price per square foot, among other things. These data are a boon for people who don’t have the time or inclination to look this stuff up, and it aggregates the data into one intelligible, quick snapshot.

I found some flaws in Trulia, like the way it accidentally listed a property that was sold five months earlier. Trulia said it relies on partners for accurate listings, and those partners get their data from Multiple Listing Services or local brokers and agents, therefore Trulia’s data are only as good as its partners’. (At least one other real-estate site also accidentally listed the already-sold condo for sale.) Another problem occurred when I tried to use the CompareIt chart on Washington, D.C., properties; Trulia said the tool doesn’t work for D.C. due to a bug that it hopes to fix. Finally, properties saved on the iPhone app won’t transfer to your Trulia Web site account. The company says it hopes to fix the iPhone issue.

Trulia’s CompareIt lets users compare five properties with one another.

One of Trulia’s competitors is Zillow.com, which displays its own price estimates for all houses in the U.S. (for sale or not) to give people an idea of the real-estate value in an area. The two sites are similar in some ways: Both show heat maps, display data about nearby schools, have mortgage calculators and use online communities to answer questions. But Zillow doesn’t offer a stat-packed Newsfeed or an iPhone app like Trulia.

After browsing through Trulia, I found a variety of properties that suited my target price range and location preferences. One place had lots of big windows and a renovated kitchen, according to the photos and information listed on its detailed Trulia Web page. A shortcut on the page made it easy for me to share this place with three friends to see what they thought. I even posed a question to the Trulia community about the property: Does this unit have a private entrance, or does it share an entrance with the five other units in the building?

Ironically, this was the property that was already sold, as I found out when a real-estate agent responded to my question. It took him just 15 minutes (Trulia says this is within five minutes of the average response time) to post a response saying that he was familiar with the listing and that the place sold five months earlier. Trulia has since updated this property’s status.

Other questions that I asked of the community were answered within 20 minutes. In one instance, I asked a general question about the best time of year to buy in Washington, D.C., and three real-estate agents responded almost immediately; two were from my area and offered their advice — and their services — but one from Florida chimed in simply to offer some encouragement. Each responder was clearly identified with a name, classification (i.e. real-estate pro) and photo. Within a couple hours, four more people responded.

These questions and answers are shared with everyone on Trulia, and I clicked on a thumbs-up icon to vote for the answer I found most helpful.

Email alerts can be set up through Trulia so you’re notified if a property you like dips below a certain price, or if there are new blog posts about certain categories like financing, crime or environmentally friendly properties.

The CompareIt tool worked to see how properties (excluding those in D.C.) stacked up against one another, up to five at a time. These charts arm people with more statistics and (likely) more negotiating power.

The real-estate world can be intimidating, now more than ever. Though sites like Trulia won’t solve this problem completely, they could make the weighty decision of buying a house a little bit easier.

This week, I tested Peek, a device that might bridge the gap between these two camps. It’s made for those who don’t intend to become consumed with mobile email, and don’t need a combination phone, Internet, digital camera and email gadget. Yet from time to time, these people wish they had a better way to check emails without going home and turning on their computers.

The $100 Peek (GetPeek.com) sends and receives emails for $20 a month.

Since I fit the constantly-checking-email description, I enlisted the help of someone who falls squarely into the category that Peek is targeting: my mother. Mom is constantly on the go, working on one project or another, and she doesn’t have time to consistently check her email. On more than one occasion, I’ve had to call her to talk about emails I sent that she didn’t yet read.

Stylish and Simple

Peek is a stylishly thin device that, to a mobile email novice, could pass for a BlackBerry. It receives and sends email, period. Peek doesn’t have a Web browser, phone or built-in digital camera. It’s sold for $100 at Target and GetPeek.com, and costs $20 monthly for contract-free service. Most email accounts work with this gadget, including Hotmail, Yahoo, Gmail and AOL, and up to three accounts can be set to work on each device.

Peek Inc., a New York company that was started by former Virgin Mobile USA (VM) employees, mailed a Peek to my mom in Pennsylvania, and she has been using it for about a week with positive results.

I, too, tested a Peek, but I was more interested in my mom’s feedback since, prior to this test, she hadn’t used a mobile email device and I use two different ones — regularly. Overall, I’d suggest waiting until November to buy a Peek due to a handful of improvements that the company plans to add by then.

Winning Over a Novice

My mom got the hang of Peek almost instantly and found it both helpful and relatively easy to use. She liked its full keyboard and the way most of its keys lit up and were familiarly placed like those on a computer keyboard — a feature I take for granted on my BlackBerry. Its price and stylish, thin look appealed to her, too. She tested an Aqua Blue Peek — though the device also comes in Black Cherry and Charcoal Gray. I knew Mom was catching on when she casually sent a message from her Peek late one night using the subject line, “What’s Up?”

My mom suggested a few improvements, and I agreed with all of them. The Peek can vibrate, chime and glow blue when new emails are received, but none of these indicators are particularly noticeable. For example, the chime sounds only once and neither my mom nor I could always hear it — even at its loudest setting — especially if it was in a purse. A blue indicator light on the Peek glows once every 10 seconds for 10 minutes after an email is received, but goes idle after that.

The font used on the Peek’s screen could stand to be a little bigger. My mom found words typed in all capital letters were easier and faster to read than the regular font, but she thought most people wouldn’t have too much trouble while using their glasses.

Peek Inc. says that by November, it will have added a louder chime, a constantly blinking indicator light and a larger font to the device. Also in November, people who purchase 12 months of service at once will get an extra month free.

Compared with my BlackBerry Curve, the Peek was thinner but I found its buttons and side scroll wheel a bit stiff. And Mom and I both found that the oft-used Space bar key was too tough to press down.

One Inbox, Three Accounts

The Peek’s straightforward system uses one inbox view (in which up to three email accounts are combined), one menu and a side scroll wheel for selecting commands. And though my mom didn’t seem to mind, the device’s overall navigation system came off as a bit clumsy to me. For example, rather than selecting an email to read it, I had to select an email, and then choose “Open Email” from a menu list. On most other devices, this can be done with one step.

But some BlackBerry tricks are built into the Peek, such as touching “T” to automatically go to the top of an email or inbox; “B” to go to the bottom; or “N” to move to the next email without navigating back to the inbox list. Likewise, the space bar serves as a built-in Page Down button. And holding a letter down will capitalize it.

Photo attachments can be easily opened on the Peek, though attached documents from programs like Word and Excel won’t open up.

Synching Contacts

A simple step lets users synchronize their email account’s contact list with the Peek. My mom did this with an AOL account, and I did it with Hotmail, Gmail and .Mac accounts. Peek devices automatically check for email every two to five minutes, or if users can’t wait two minutes, they can initiate a Send/Receive manually and see an up-to-date queue of emails.

Peeks each have eight megabytes of usable memory, which can hold about 5,000 emails. Once a device reaches capacity, an on-screen prompt asks permission to delete the 500 oldest emails. Peek Inc. says a full battery charge will last about five days if a device handles around 10 to 15 emails a day; power users who send and receive 200 to 300 emails a day will get about two days of use from a full charge.

When asked, my mom concluded that she would probably buy a Peek, but said she still wasn’t sure that she had an urgent need to see email all that often. She also noted that Peek could become a Pandora’s box of sorts for people who, as they use it more often, might want to get more out of it — such as Google searches or other Web browsing.

Peek serves a purpose: It gives those who don’t belong to the “I-check-my-email-constantly” club a way to “peek” in on their emails and not feel so unplugged from friends and family. That alone, is reason enough to buy my mom one of these devices.
