I have one. It's too heavy and bulky for a mouse, and too flat & unergonomic for a keyboard. There are lots of pinky keys I find very difficult or impossible to reach when the hand is resting in the natural position on the device. And you don't want to move the hand too much around or you end up moving the mouse... Honestly the tiny little mouse buttons suck too.
