In his keynote at the Bluetooth Developers Conference earlier this month in San Jose, Calif., IBM Distinguished Engineer John Karidis impressed me with a display of the companys Bluetooth-enabled Linux wristwatch. Karidis used the prototype watch, which runs a stripped-down version of the Linux 2.2 kernel complete with X11 graphics, to control the slides he used in a video presentation.
I dont expect to see the watch in stores any time soon, but the demo offered a tantalizing taste of Bluetooths real-world usefulness and showed that the technology is maturing quickly.
