A handheld-PC, portable-PC, pocket-PC, PDA, or otherwise small 9"-10"-ish wide laptop that uses AAs, has as long a battery life as possible and is lightweight, qwerty keyboard, and quiet.
Some options I'm looking at right now:
Casio Cassiopeia A-21S Handheld PC
NEC Mobilepro 780 Portable Computer
Tandy TRS-80 Model 100
