I have a couple of the m-sys 144mb disk-on-chips booting redhat linux! 
And I use a dual PCMCIA reader to add more storage via pcmcia hard 
drives. It's pretty amazing, you can make an entire pentium machine in 
about the footprint of a 3.5" hard drive. I have one that is becoming 
a controlleer for a walking robot and another built into a small lunchbox, 
it has a 4x20 vacuum flourescent display, 5x5 keypad, and wireless radio 
modem. I am soon going to use it to do all my work on, it has 2.1GBs
and all kinds of networking goodies. I wrote some code last week that 
queries sensors at my home and displays them in real time on the 
character display (weather, home monitoring, aquarium monitoring, the
state of various devices etc). This weekend I wrote some code that
interfaces with GPS and send positional data back to my server at home. 
It works all over the SF bay area with no wires, pretty cool. It is an
experiment in people tracking. :)  The really cool thing is that I have
code running on both sides (server at home and mobile wearable) and 
they are always connected, communicating back and forth regularly.

PS. The 144mb disk-on-chips are expensive. Almost $500 a pop.
