Let's face it. A TRS-80 Model 100 in many ways is probably still the ideal portable writing machine. Only displays a couple lines at a time so you can't get too distracted with formatting and such. Rugged, full keyboard, 20+ hours of battery life, and reasonably easy to read even in full daylight. While I have migrated to an iPad 2 for many things, I sometimes wonder if that really represented an improvement...
