The Combimouse.

What do you get when you combine a keyboard and a mouse? Well, you get this weird gadget which purpose is to eliminate the needs to switch back and forth between the two devices (very useful for Exel spreadsheets, apparently).

The left unit is stationary and provides the function of the left hand side of a conventional QWERTY keyboard. The right unit has a similar mass and centre of gravity to a conventional mouse. It also has a similar grip.

The combimouse right unit is a mobile combination keyboard and mouse that can be moved around on a support surface like a conventional mouse. The keys are arranged in the fashion of the right hand side of a conventional QWERTY keyboard.
