does anyone remember the device from the mid 80's that had 5 keys and could be held in one hand (although not for very long because it was heavy). They had a system similiar to a stenographer that meant pressing a combination of the 5 keys created a letter. it was supposed to be very fast and very easy to learn. Let's face it the keyboard layout is as inefficient as it could possibly be having been designed to slow typist down to stop typewriter striking arms from jamming.

how about the palm graffitti hand writing input?
