Samsung's i900 Omnia

For starters, the phone auto-rotates to 3 of its 4 sides in a unique way. Instead of using an accelerometer to detect this kind of motion, the Omnia instead makes use of its 5 megapixel camera. This is similar to the way that the Samsung Instinct for Sprint uses its camera for panning and scrolling in its browser.
The full opera browser should look quite nice on the Omnia's 400x200 pixel widescreen, and the 5MP autofocus camera supports features like image stabilization and Samsung's wide dynamic range. We're still missing specs on weight and battery life, but most of the details have been filled in at this point. In any case, take a look at the video below
