The Lenovo K900 is a big phone, yes, but it's a designy big phone. It's handsome, skinny, and slick like the finest smartphones ever made. We never thought we would be into a 5.5-inch phone until the K900's brushed metal back landed in our hands.
This phone is all about the hardware. The unibody construction is completely smooth and flat, unlike other large, long phones. In fact, Lenovo says that at just 6.9mm thick, it's the thinnest in its class. It weighs just 5.7 ounces.
The Full HD, 400ppi screen is amazingly satisfying. As you can see in the images, the IPS display blends beautifully with the black bezel. On the reverse, the back panel is totally without bumps, which is impressive on such a slim construction. Not even the camera pokes out. (Speaking of the camera: it shoots with a 13-megapixel Sony Exmor sensor and has a super fast f/1.8 lens.)
The K900 runs an Intel Atom z2580 processor, and it was wasn't final so we don't know anything about performance. Sadly, we don't even know what operating system the phone will run, let alone when I'll be able to see if it fits into my skinny pants.
