Lenovo has just announced the IdeaPhone K900, a 5.5-inch smartphone for the Chinese market with a dual-core Intel processor. The K900 is one of the first phones on the market with Intel's new 2GHz dual-core Atom processor, the Clover Trail+, and its display features 1080p resolution and a pixel density of over 400ppi. The phone is remarkably thin at only 6.9mm, which Lenovo claims is the thinnest for its class. Using both stainless steel and polycarbonate, the K900 is sharp and square where its competitors are soft and rounded.

Lenovo claims that it has "maximized the opportunity to be the first to market with the new generation platform" with the K900's Atom processor, and it insists that the phone is very responsive for activities such as web browsing and running apps. It appears that the K900 has a similar camera to the recently announced Sony Xperia Z, as it is 13-megapixels in resolution with a Sony Exmor backside illuminated sensor and bright f/1.8 lens.

In your hand, the K900 feels really thin, but otherwise reminds us of a metal version of the aforementioned Xperia Z. Users can customize its appearance with four different metallic backs. We handled an early prototype version of the phone, which which was running Android 4.1 with a custom user interface; we've been told it'll be running 4.2 by launch. Interestingly enough, the skin can be turned off if you aren't a fan of Lenovo's interface design. Unfortunately, we weren't able to get any idea of the new processor's performance because of the early prototype state of the device. Lenovo says that it will be available in China beginning in April of this year, but pricing information is not yet available.
