The concept behind 
the CharmIT Pro wearable computer is 
one that follows along with the open source programming community closely, but 
in this case with hardware. The CharmIT Pro is a open source Crusoe based 
wearable built with off the shelf components like an SBC from Boser and created 
from the minds at MIT's Media Labs. The unit shown here (about $2400USD) is 
a professional version of the same device, and comes in a custom, 
heavily ventilated carry pack.  
The CharmIT Pro uses an 800MHz TM5800 Crusoe processor and contains 256MB SDRAM, a 20GB 
hard drive, and an SBC motherboard which boasts 10/100 Ethernet, serial ports, 
USB ports, a 32-bit Mini PCI expansion slot, and video controller. Battery life 
for the 1.75lb unit wasn't specified, and we weren't able to track down the 
'Charming rep' for this bit of kit at the time of the PCexpo 
event. 

 Mainstream consumers may look at this 
and wonder what the gig is, but I showed this picture to our Linux guy and he 
lit up like a Christmas tree. Wearable computers running Linux with cool Crusoe 
processors are pretty hard to resist for some techies.
