oddly shaped laptop sits in stark contrast to many of the sophisticated, business-like ultrabooks debuting at CES: it's fun (well, that's how the company characterizes it). Part tablet, part ultrabook, the Yoga features a 360-degree flip-and-fold design that allows users to switch back and forth between using a touchscreen and a keyboard, which doubles as a stand.

HP Spectre

HP debuted its latest ultrabook

at CES late Monday, a sleek, super-skinny consumer laptop. The No. 1 PC maker calls its new model the Envy Spectre, a name intended to "evoke mystery," according to the company.

"Sleek, midnight black glass on the outside and stark contrast silver glass on the inside make Spectre extraordinary, defying conventional notebook design," explained Eric Keshin, senior vice president of strategy and marketing at HP's Personal Systems Group.

Aimed at the consumer market, the Envy Spectre comes with a 14.4-inch high-definition screen and Beats Audio technology, as well as built-in HP Wireless Audio. HP says that the Wireless Audio feature can "turn any home into a concert hall," letting users stream uncompressed audio to up to four external devices.

Lumia 900.

Surfacing Monday, the phone is Nokia's first Windows 4G LTE model. The 16GB device is equipped with a 4.3-inch AMOLED display and a 1.4-GHz processor, and will run on AT&T's network.

More Motorola Droids

Motorola continues its Droid rollout with the RAZR Maxx and the Droid 4. The Droid 4 boasts a 4-inch screen and a slightly updated slide-out, back-lit QWERTY keyboard.

The Razr Maxx builds on Motorola's score with its recently re-introduced RAZR phone and adds a potentially huge feature: A giant battery. While the first Droid RAZR had a 1700mAh batter, the Maxx boasts a 3300mAh. Verizon says that the Maxx will offer around 21 hours of continuous talk time on one charge -- but only time (and testing) will tell.

Timing of when the two phones will hit stores was vague -- "in the coming weeks" -- and pricing, not available for the Droid 4, is $299 with a two-year contract for the RAZR.

Microsoft Kinect

Priced at double what the original Kinect for X-Box cost, Microsoft's latest iteration -- Kinect for PCs -- will sell for $249.99.

Announced late Monday

, Kinect will be available for Windows on Feb. 1 and is aimed squarely at corporations. "Kinect for Windows will also support gesture and voice on Windows Embedded-based devices and will enhance how data is captured and accessed within intelligent systems across manufacturing, retail and many more industries," said Microsoft at CES. "We are building the Kinect for Windows platform in a way that will allow other companies to integrate Kinect into their offerings and we have invested in an approach that allows them to develop in ways that are dependable and scalable."

It's available for pre-order now in the United States, Australia, Canada, France, Germany, Ireland, Italy, Japan, Mexico, New Zealand, Spain, and the U.K.
