One of the things holding back my cyborg project is the cost of the hardware. I may have found a way to address that problem though, through a stop-gap measure.
How? With this
Zipit wireless IM device.Although limited to IM by default,
this page has information on installing linux on it. From there, you could SSH into a real computer and have some real power and resources available to you. Some additional info is available
here.
The specs put the screen on this at 1/4 VGA (320x240 grayscale LCD), so a modified software set will probably be required. Something along the lines of
G Linaccess, probably.
I still have some more research to do, but this $100 device may be able to bring me a tiny step closer to my goals. Obviously, it lacks the video capabilities I'm looking for long term, but it could potentially address most of my data access needs.
