Lenovo IdeaPad YOGA Flip (Preview)

Pros: Unique design offers both laptop and tablet form factors; 8 hours of battery life; high resolution (1600 × 900) screen

Cons: Heavier and bulkier than any tablet

Preliminary Rating: Four out of five stars

Recommendation: Lenovo describes the IdeaPad YOGA Flip as "the industry's first multi-mode notebook." Its 360-degree, flip-and-fold screen design lets it function as a normal laptop computer or the screen can be flipped around, like a convertible laptop. Or it can be used in a unique new tent mode in which the the device acts as its own stand in a multi-touch tablet form. Lenovo says the YOGA Flip supports four separate usage modes. Detractors say that its 3.1 pounds can’t compete with iPad and Android tablets, but that's missing the point: The YOGA Flip is a laptop first, tablet second. Looks good to me.

Nokia Lumia 900 (Preview)

Pros: Innovative design, superior screen, LTE 4G capabilities, unique Nokia-only apps

Cons: Only available on AT&T, at least temporarily; low 800 × 480 screen resolution

Preliminary Rating: Four out of five stars

Recommendation: The Lumia 900 has the same beautiful polycarbonate casing as the Lumia 800, but in a slightly bigger package (in blue/cyan and black versions). Its 4.3" AMOLED screen is superior to the one on the 800, but retains the same 800 × 480 resolution, as mandated by Windows Phone. It has an excellent 4G LTE antenna for compatibility with AT&T's network. It has a large 1830 mAH battery for longer-lasting performance. And best of all, its camera offers Carl Zeiss optics, a large aperture (f2.2), and a wide-angle focal length (28mm) for what should be high-quality images even in low-light conditions. This is the premier Windows Phone. I'm buying one March 18 when it becomes available in the US.
