Split keyboards aren't new. Neither are keyboards with integrated pointing devices. However, I have never seen a mouse that is essentially one-half of a split keyboard, with some of the keys doubling as mouse buttons. I'd really like to get my hands on one of these; I'm already completely in love with the concept. Check out the Combimouse site for more info, including a usability study and an all too-brief video of the device in action.
