Quite off-topic, but probably of interest --
For small Unix machines, how about the wristwatch that runs Linux and
uses X11 for the display, developed at IBM?
The original prototype used a small backlit LCD display, but the latest
version uses an Organic LED (OLED) display that is absolutely stunning!
The machine runs with an ARM 7 CPU (Cirrus Logic EP7211), 8 Megs of
flash memory and 8 Megs of DRAM. The OLED display is 640x480. It has a
built-in Bluetooth transceiver, Lithium Polymer rechargeable battery, a
combination of touch screen and a jog dial for user interface, infra-red
interface. The watch 'program' is 'xclock'!
There's a great article (with lots of pix) about the development in the
latest edition of IEEE's "Computer" journal (January 2002).
