okay i just read some comments on engadget, and it sounds as if this thing moves around every once in a while to make sure that your wrists aren't always in the exact same position. i just can't help be cynical about this thing though. i mean, if i wanted to change my position i could just move myself, or adjust the feet of my keyboard. are we, as humans, that lazy that we can't do that? anyway, i think it would be rather strange if my keyboard just started moving around. i'd end up hitting the wrong keys all the time. and i'd be forever wondering "is it about to start moving!?", which would be quite the distraction.
