The DataEgg is a round, one-handed, chording computer with a two-line LCD
display (similar to the Microwriter AgendA). It can also serve as an
alternative computer keyboard through a computer's serial port (currently
supporting the PC, although it wouldn't be too hard to support X or a Mac
if they wrote the driver). InHand will be manufacturing the device, which
was originally developed by Gary Friedman of JPL.
