I think there is an additional, and more important, barrier to paper's demise. copyright. If the ideal display were announced tomorrow, paper would still exist because you can't get information from publishers in digital/on-line form.

I've read about an 80x25 character head mounted display that is small, light, and cheap. It used a single column of LEDs and a rotating (or vibrating?) mirror.

This technique is used in high-performance multi-million $ flight simulators, where the screen is being constantly recomputed. It doesn't really apply if you're using something like X. It's esoteric and expensive in any case. Consume Scott Draves Be Silent spot@cs.cmu.edu Die
