I have been meaning to play with an alternative input method for a PC for a while. I have come across plenty of stuff that other people have done - so what I am trying is by no means new.

I came across a cute mini wireless USB keyboard on Hacked Gadgets. Its small enough to fit into a glove box, and provides a touchpad as well as a small keyboard for data entry.

You can buy them at EFO or on Ebay.
