Samsung Spring Preview
The X810 is one of several Samsung music phones with an iPod-esque spinning scroll wheel.
The X810 is also notable for its amazingly small size. It's a bit thick, but its narrow width makes it still quite a small phone. Unfortunately that makes the display a bit small and cramped. It's still an engineering marvel, though, especially since it sports built-in stereo speakers and and a unique swivel part that houses both the camera and ear speaker.
The X810 has a solid feel to it, which is only enhanced by the spring-assisted mechanisms for both the slide and the rotating camera.
Unfortunately the X810 is only available in limited distribution; France is one of the few countries where it's for sale so far.
