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.

But just how good is Chrome? How does it differ from IE and from less popular, but still important, browsers like Mozilla’s Firefox and Apple‘s Safari?

I’ve been testing Chrome for about a week, trying out all its features and using it side by side with Microsoft’s latest iteration of IE, which came out just last week.

My verdict: Chrome is a smart, innovative browser that, in many common scenarios, will make using the Web faster, easier and less frustrating. But this first version — which is just a beta, or test, release — is rough around the edges and lacks some common browser features Google plans to add later. These omissions include a way to manage bookmarks, a command for emailing links and pages directly from the browser, and even a progress bar to show how much of a Web page has loaded.

Chrome’s interface has some bold changes from the standard browser design. These new features enhance the Web experience, but they will require some adjustment on the part of users. For instance, Chrome does away with most menus and toolbar icons to give maximum screen space for the Web pages themselves. Also, Google has merged the address bar, where you type in Web addresses, with the search box, where you type in search terms. This unified feature is called the Omnibox.

One striking difference in Chrome is how it handles tabs, which display a single Web page. In Chrome, each tab behaves as a separate browser. The bookmarks bar, Omnibox, menus and toolbar icons are located inside the tab, rather than atop the entire browser. The tabs appear at the top of the computer screen. Chrome also groups related tabs. If you open a new tab from a link in a page that’s already open, that new tab appears next to the originating page, rather than at the end of the row of tabs.

Despite Google’s claims that Chrome is fast, it was notably slower in my tests at the common task of launching Web pages than either Firefox or Safari. However, it proved faster than the latest version of IE — also a beta version — called IE8.

Meanwhile, Microsoft hasn’t been sitting still. The second beta version of IE8 is the best edition of Internet Explorer in years. It is packed with new features of its own, some of which are similar to those in Chrome, and some of which, in my view, top Chrome’s features.

Google’s Chrome browser displays thumbnails of a user’s most-visited pages when a new tab is opened, rather than a blank page.

For example, while IE8 also groups related tabs, it assigns a different color to each such tab group and allows you to close them all with one click. It has a “smart” address box of its own, that drops down a list of suggestions as you type, though it retains a separate search box.

IE8 also has breakthrough privacy features that exceed Chrome’s, and includes a new technology called Accelerators, which allows you to take rapid action on any selected word or phrase on a Web page, such as generating a map for a place name, without switching to a new page.

As they develop, each of these browsers has a good chance of besting Firefox 3.0, which I have regarded as the best Web browser for Windows, the only operating system on which Chrome currently runs. But they will have to get faster at loading pages. And, to best Firefox on the Macintosh, Google will have to make good on its promise to produce a Mac version of Chrome, something it says it will do in the coming months. Microsoft has no plans to produce a Mac version of IE8.

Chrome and IE8 are far more advanced than Apple’s Safari. Safari is speedy on both Mac and Windows platforms, but lacks many of the key intelligent features of its newer Google and Microsoft rivals.

Why is Google igniting a new browser war? There are two main reasons, and both involve competing with Microsoft. First, the search giant fears that because its search engine and other major products depend on the browser, Microsoft — with its rival online products — might be able to gain an advantage by altering the design of IE, which has roughly a 75% market share.

Second, and more important, Google sees the Web as a platform for the software programs, or applications, that currently run directly on computer operating systems, notably Microsoft’s Windows. It says current browsers lack the underlying architecture to enable future, more powerful Web applications that will rely more heavily on a common Web programming language called JavaScript. Chrome was designed to be the world’s speediest browser at handling JavaScript.

That move might one day make Chrome a sort of online operating system that competes with Windows. “Think of Chrome as more than a simple Web browser,” Google declares. “It’s a platform for running Web applications.”

Microsoft’s IE8 has an “Accelerator” feature that lets users select any Web text and then map, translate, search or email their selection without leaving the page.

I tested Chrome, and IE8, on a plain-vanilla Lenovo ThinkPad laptop running Windows XP, and equipped with a modest processor and one gigabyte of memory.

To gauge Chrome’s speed at loading Web pages, I launched two large groups of typical Web pages simultaneously, each site opening in its own tab. One group included 15 sports sites, the second 19 news sites. In both tests, Chrome’s speed fell in the middle, at 35 and 44 seconds, respectively. IE8 was slower, taking 49 and 75 seconds to open the two groups of sites. But Firefox and Safari were much faster, notching identical speeds of 19 seconds for the 15 sites and 28 seconds for the 19 sites.

Google claims that future, more sophisticated Web applications relying more heavily on JavaScript than today’s sites do would run faster on Chrome. Of course, I couldn’t test any claim about future scenarios, but I did run Chrome on several JavaScript test sites, used by developers. It handily beat the other browsers. However, Google doesn’t claim users would see much difference on current Web application sites.

I also tested Chrome’s compatibility with scores of common Web sites. In general, it did well, rendering the sites properly. But I ran into problems with video. Some video sites refused to recognize Chrome, because its development has been a secret. On others, like Major League Baseball’s site, videos mostly played properly, but sometimes didn’t.

IE8 also has some compatibility issues, for different reasons. It’s the first version of Internet Explorer to hew closely to Web standards. Earlier versions used some nonstandard ways of rendering Web sites, prompting some site designers to adopt techniques that made their pages work in IE, but look odd in Firefox and Safari. Now, ironically, these pages also look strange in IE8. So Microsoft was forced to build in a special Compatibility View button that users must click to see the sites properly.

Chrome is built on three core design principles. The first is its spare user interface: just two menus and a handful of toolbar icons. IE introduced a similar approach in its version 7, but with a difference. Microsoft allows users to restore a traditional menu bar; Google doesn’t. The only toolbar icon you can add in Chrome is a Home button.

The second principle is that a user can type anything into a single place, the Omnibox, and instantly get suggestions on where to go, gleaned from the user’s own browsing history and Google’s rankings of popular sites. Whether you type in a Web address or a search term, the Omnibox is very smart. In my tests, it sometimes came up with the right destination after I typed only one or two letters of the name of a site I often visited.

The Omnibox has another cool feature: Tab-to-Search. If you type in the name of another site that includes its own search feature, like Amazon.com, the Omnibox lets you just press the tab key to search within that site, without opening it first. Chrome, through its Options settings, also lets you change the default search engine used by the Omnibox. Instead of Google’s own search service, you can use Microsoft’s Live search, Yahoo search, or others.

The third big principle behind Chrome is that each tab runs, under the hood, as a separate browser. Tabs can be dragged off the main browser and turned into separate windows. If one tab crashes, the rest of the browser keeps running. But this doesn’t work perfectly. In my tests, all of Chrome died on me when I tried watching an Olympics video on the NBC site.

You can even make a tab a standalone application that runs from the Start Menu, or the desktop, as if it was a separate program.

Chrome has a few other key features. When you open a new tab, you don’t get a blank page, but a set of thumbnails for your most-visited pages, plus lists of recent search engines you’ve used, recently used bookmarks and recently closed tabs.

Like other browsers, Chrome puts up a warning when you try to visit a malicious or phony Web site, and it has a private browsing mode, called Incognito, which allows you to browse without leaving any history on your computer — a feature popularized in Safari.

Chrome also has a pop-up blocker, but it’s annoying because it flashes a notice that a pop-up has been blocked. IE also does this, but unlike in Chrome, the warnings are much less intrusive.

Internet Explorer 8 has some new features Chrome lacks. Its private browsing mode, called InPrivate, is the first I’ve seen that not only leaves no traces on your own computer, but also bars Web sites from collecting some types of information on where you’ve previously been surfing.

While IE8′s address box and search box remain separate, each also offers rapid suggestions; and both are organized better than Chrome’s. For instance, the suggestions that drop down from its address bar are divided neatly into categories drawn from the browser’s own guess, your history and your favorites. One downside: For this to work in Windows XP, you must first install Microsoft’s desktop search product.

Like Chrome, IE8 lets you switch your default search provider, but it also allows you to switch search engines on the fly. When you type in a search term, icons for alternate search engines appear at the bottom of the suggestion list, and you need only click on these to see search results from, say, Google, instead of Microsoft’s own Live search engine.

IE8′s Accelerators feature presents a blue-arrow icon above any text on a Web page that you have selected. Clicking on the icon brings up a list of actions you can take using the selected text, such as posting it to a blog, emailing it, mapping it or searching it. While these actions are set by default to use Microsoft’s own Web services, you can change them to use Google’s, Yahoo’s, or those from other companies.

Microsoft also has built in a feature called Web Slices. These are portions of a Web site that a site developer can designate to appear in the IE8 Favorites bar and to constantly update themselves. An example might be bidding on eBay.

Like Chrome, IE8 also displays useful information whenever you create a new tab, including a list of recently closed tabs and a list of Accelerators.

With the emergence of Chrome, consumers have a new and innovative browser choice, and with IE8, the new browser war is sure to be a worthy contest.

I headed online to start researching (I was looking for a used car) but was overwhelmed by an avalanche of information. Everyone seemed to have something to say about cars, whether in blogs, community forums, editorial reviews, Kelley Blue Book values, Carfax reports or local dealer sites. As I discussed my findings with friends and family, more people than not were surprised to hear about the variety of research and price comparisons available online.

This week’s column is an overview of sites that may help you or someone you know browse for a new or used car on the Web. I used sites ranging from trusted resources like ConsumerReports.org to search engine tools like Yahoo Autos. This column can’t possibly mention every car-searching resource on the Web; rather, it’s just a taste of what’s available.

Edmunds.com and ConsumerReports.org both feature informative data on a number of new and used vehicles. Edmunds is a free site specifically geared toward cars, including an online magazine for enthusiasts called Inside Line and a Web forum for discussions about automobiles called CarSpace. I used various tools on Edmunds.com, including one that estimates the true cost to own a specific car over time. I especially enjoyed reading an article titled “Confessions of a Car Salesman,” which proved uncanny in predicting a range of tricks and techniques the salespeople used when I first visited a car dealership.

Edmunds offers a four-step pricing system, which includes getting quotes from dealers, and a payment calculator, which estimates monthly payments. Edmunds teams up with AutoTrader.com to help perform searches for certified pre-owned or used cars online.

Consumer Reports covers products as well as cars but keeps much of its most useful data behind a Web-site subscription, which costs $26 annually or $5.95 monthly (magazine subscribers can pay a discounted price of $19 a year). You need this subscription to access CR’s respected ratings and certain sections of its Web forums. These ratings were helpful to me, as they assessed numerous aspects of specific car models, including trouble spots by year, performance, safety and fuel economy.

CR also offers valuable lists such as “All Recommended Cars,” “Best and Worst Used Cars” and “Reliable Used Cars by Price.” A car-buying calculator is an asset to this site that helps you decide whether it would be smarter to buy or lease a vehicle.

Google, Yahoo and AOL all present special search-results pages when you search for a specific car for sale, using drop-down menus and various ways to sort results. Google Base for automobiles, found by selecting “Vehicles” from www.google.com/base, is a list of data submitted to Google. Drop-down menus help broaden or narrow results by sorting the data according to certain attributes, such as make or price. Vehicle-search results can be viewed in one of three formats: List View, Table View or Map View — an illustration of each car’s location in relationship to a Zip Code. I found Table View most useful because it organized data in smart, spreadsheet-like displays so I could quickly skim through columns listing price, color, amenities and mileage.

But not all car searches within Google Base returned the same drop-down-menu options for sorting. In a few instances, I couldn’t sort my search results by model year. Google Base does show the date on which each car was listed.

Yahoo Autos, found at www.autos.yahoo.com, teamed up with Cars.com to offer richer content, including a Car Finder feature that helps people narrow down what type of new car they might like according to price, driving style and fuel (type and economy). Yahoo even tries to answer car questions with its Yahoo Answers Q&A tool, which lets people submit questions. I found user reviews on this site, as well as expert reviews provided by NewCarTestDrive.com, an auto-review site.

The used-car section in Yahoo Autos reminded me of Google with its drop-down menus and results that displayed in list or map views. List view shows plenty of information in one glance, including an image of the car for sale and the number of additional available photos. From this list, users can link directly to view or order Carfax reports or email the dealer, saving time wasted on excess mouse clicks and browsing.

AOL Autos, found at http://autos.aol.com, does a nice job of integrating Web 2.0 features such as pop-up menus that appear within a page rather than in an entirely new Web page. Vehicle-search results are found by entering a few criteria for a new or used car, and used-car results can be further narrowed by adding or subtracting desired specifics listed on the far left of the screen. Some specs include model type, engine, year or extras like heated seats or a sunroof.

This site can also condense numerous used-car listings into one graph that illustrates car prices in relationship to mileage or year. Selecting any point on the graph reveals a short description of a vehicle’s location, price and mileage. For new cars, AOL Autos offers lengthy expert reviews from NewCarTestDrive.com, as well as user reviews.

Both Yahoo Autos and AOL Autos walk users through steps to get price quotes from dealers for new cars.

Carfax.com provides car-history reports using vehicle-identification numbers, or VINs. For a $30 fee, used-car buyers can use Carfax.com for 30 days. This report shows a vehicle’s history such as if it was a rental or not, how many different owners it had, how long each owner possessed the vehicle and where it came from. Tips pop up within these reports, including one that warned me about “curbstoning,” a term that describes an individual without a dealer’s license looking to sell a number of cars by posing as a private seller.

As can be expected, many newspaper Web sites offer automobile sections that display digitized classified ads, so be sure to check your local paper’s Web site.

At the end of the day, test-driving a car will be a true test as to whether or not you like it — no matter how much research you’ve done online. But knowing your stuff before you visit a dealership can save money and time.
