Too busy to drive? Let the car take the wheel. PopSci recently went for a ride in the Chevy Boss, winner of the 2007 Darpa Urban Challenge. With tricked-out GPS, sonar, laser guidance and a stack of computers, this 2007 Chevy Tahoe SUV can navigate an urban setting, weave around obstacles, and even negotiate intersections with other cars. GM expects the technology to be affordable, and less obtrusive, in about a decade.

Even if you think the Bose Sound Dock is the pinnacle of audio clarity, you can't find a more pleasant way to spend an afternoon at CES than touring the high-end-audio area, moved last year from a sketchy off-Strip motel to the Venetian. There are no flat-panels in sight. No pushy PR people. No throngs. Just room after room of equipment you can't afford, all set up simply for you to sit and listen to unbelievably realistic reproductions, for as long as you like.

I knew that GM had built real, road-ready hydrogen fuel cell vehicles. But I didn’t really believe it until I saw one, and drove it.

The Chevy Equinox I piloted—one of about one hundred that GM will put on the road later this year—looked as polished and user-friendly as any new car on the lot. It’s a comfy, soccer-mom/dad vehicle that seems like any other small SUV until you turn the ignition—err, I mean the key. There is no ignition.

While most of CES is devoted to all things geek, there is one hall where the more macho gearheads come out to play every year: the temple to high-watt subwoofers and tricked-out rides that is the North Hall.

Your next cellphone could have a 100-inch screen—without getting an inch bigger. Microvision's tiny PicoP projector can turn a wall, tabletop or any other surface into a display. It's small enough to fit in pocket-sized gadgets because it uses lasers, which sip power, are extremely bright, and produce little heat. They also do away with bulky lenses: The pinpoint beams are always in focus, from any distance.

Every year, television innovations make up the backbone of every major consumer-electronics player's booth. And for good reason—we've been buying televisions for well over 50 years now, with no sign of slowing anytime soon. Try saying that about any of the other product families at CES—”personal computers are practically infants in comparison.

This year, the race for the biggest picture is as heated as always, although the parade of massive, mini-Jumbotrons are now sharing the spotlight with razor-thin OLED sets.

I went by Lenovo’s booth to check out their new laptops, and it turned out that their laptops checked me out instead. That’s because the laptops use your face, in addition to your password, as a security measure. As soon as you approach, the webcam takes your picture. Then face-recognition software called VeriFace compares your pic to photos of authorized users. If they match, you can log into the computer. If they don’t match, it’s a double whammy: Not only can you not log in, but the PC saves your pic, so the real owner can see who’s been snooping around her laptop. The tech showed up on a couple of Lenovo’s business-y ThinkPad laptops last year, but is about to make a much bigger showing now that Lenovo’s releasing its first consumer laptops for the U.S.—Lauren Aaronson

On the one hand, Vegas does gaming really, really well. On the other, well, maybe it's not its strong suit. Even though gamers may get less CES love than the larger gadget crowd, if these products are any indication, they shouldn't feel short-shrifted; it's quality.—Abby Seiff
