Ari Zagnoev’s Combimouse is a keyboard and mouse arranged in an odd sort of way. The right unit is the right side of a QWERTY board that can be moved around for comfort and operates in keyboard mode unless it is switched. The company calls the switch “effortless and intuitive.” We call it one more thing to fall off the desk, although they say it was tested by college students who found it convenient. By the way, they are also looking for investors if you think they have a hit on their hands.
