The SliMouse SlimPad doesn’t just look odd because it is a square shaped mouse, it realy is pretty odd because instead of using a scroll wheel it has a sensor touch-scroll. The sensor touch-scroll claims to allow greater precision and ease of control. There are two Slim Pads available - a Model I with a wire that stores inside of the mouse when not in use. And there is a Model II which is wireless. There is no release date or pricing yet available for the Slip Pad, but it looks like it’s starting to be hip to be square.
