IBM’s Linux-powered wristwatch PDA: “…no ordinary wristwatches, however. On one hand, they’re bulkier, and the

rechargeable lithium-polymer battery lasts only two to four days. Yet the watches have as much

memory and storage space as an older desktop computer. In two years, IBM expects battery life to

improve to last several months…

About two-dozen of the prototypes have been created so far. The watches run on an ARM-based

EP7211 processor made by Cirrus Logic and have 8MB of memory to run programs and 8MB of flash

memory to substitute for a hard disk. The watches also include an infrared and wireless radio

connection and a touch-screen display. The watch can tell time and has a calendar and to-do list that

can remind the wearer of appointments…” A photo is here.
