Actually, the keyboard of the future will probably be something along the lines of something I just saw in a catalot for computer supplies. It was a computer keyboard that was made of rubber and just rolled up like an old newspaper. All the keypads were rubber, the entire board was rubber and it had a thin wire that went to the computer.
The same thing could be done with keyboards, the difference being the guts of the board would be in a small module that would be completely separate. Who knows, you may soon be packing your keyboard around in a small tube. Then, when you get to the job, you just unroll the board, plug it into the module and you're ready to go.

The only drawback is the folks that were always complaining about the keys feel would go completely bonkers.

Cheers,
