A Lenovo laptop that knows your face
I hate passwords. Or more correctly, I hate how many passwords, PINs and security codes/answers I have to remember.
There are passwords and access codes to get into my home and office computers; my cell phone; my work and personal e-mail accounts; my home, office and cell phone voicemails; my online bank accounts; my wireless home network equipment; my accounts with Web sites such as ConsumerReports.org and this blog...
Maybe that's why I was very interested in the Lenovo IdeaPad Y510, one of the latest notebooks Consumer Reports is testing for our upcoming laptop computer Ratings update. Its most unique feature: It uses your face as the key to personal computer security.
The IdeaPad uses VeriFace, a "facial recognition" program installed in the IdeaPad. Put simply: You register yourself (and anyone else that you want to have access to the laptop) by letting the software "scan in" the faces in front of the built-in, 1.3-megapixel webcam. Those facial images can then be associated with logins—to a Windows Vista "user" account, for example. That way if you've set the Lenovo to "lock" after a period of inactivity, getting back in is as simple as facing the webcam at the top of the IdeaPad's 15.4-inch LCD screen. This facial recognition scheme can also be used to log you into your Web-based e-mail and other accounts that normally require you to type in a user name and password.
You can review how the Lenovo IdeaPad works by watching our video using the player embedded in this post.
As with other biometric-based security devices (such as fingerprint scanners), VeriFace worked well and wasn't spoofed by simple trickery. But this 007-type approach to PC security wasn't completely flawless. (Hint: Those who wear hats and reflective glasses or typically use their laptops in badly-lit places might have second thoughts about facial recognition security.) And VeriFace still requires typed-in passwords as a back-up means of access—which means it is no less vulnerable to hackers and code-cracking software.
We're still testing the Lenovo IdeaPad and will include it in our Ratings of laptop computers soon on ConsumerReports.org. But one shortcoming that was obvious to me and other testers: Its LCD screen reflected light—a lot. Under our video studio's bright lights, the screen acted like a mirror. Perhaps that's so you can better examine your face before telling the Lenovo's VeriFace software, "I'm ready for my close-up."

XP loyalists take heart -- if you’ve been hesitant about buying a new system because you don’t want Vista, take a look at Dell’s Web site. The company is offering four Inspiron and two Dimension models with XP as an optional operating system. Gamers or others looking for high-end systems will find XP on a few XPS systems.

When you attend a show like Macworld, it's very unlike the CES experience because there is a different focus. Despite the Apple name change, and the firm's gaining ground in the consumer electronics market, the Macworld Conference itself is still very much about software — innovative, creative application solutions for office, home and play. This is what one sees most on the show floor at Moscone Center, lean and hungry developers vying shoulder-to-shoulder with established software giants for the Mac consumer's dollar. Then, of course, come the hardware peripherals and the "accessories" for Apple products, from Mac hardware "modding" (see picture) to protective cases for your iPods, to designer bags to carry them all. There's tech books, there's food, there's even a place to get a massage. "Gadgets", as we've come to understand them, are fewer in number here than at a trade show like CES (unless of course you think an external hot-swappable 4-disk mini-RAID unit counts as a "gadget" — I might). But with diligence, one does run across the occasional gem.

Both Microsoft, which makes the operating systems used in most personal computers, and Apple, which provides its own OS for its Mac computers, will be rolling out new operating systems this year. CR's Tom Olson will be sharing his expectations for Apple's upcoming OS X 10.5 Leopard, which will likely be a centerpiece of MacWorld next week.
