Charmed Technology, founded by MIT Media Lab graduates, announced what it claims is the world’s fastest wearable computer — 800Mhz Crusoe TM5800 processor. The CharmedIT comes standard with a 266 Mhz Pentium MMX for about $2k. The Crusoe upgrade costs another $500. The OS is extra ($250 for RedHat or Debian), as is the display, input device, carrying case, battery, charger, usable application … if that isn’t enough options, you can also get a DIY kit.
