I've never been able to take notes on the computer. I get way too distracted. "OOH! Internets. OOH! Someone's online, let me chat with them. OOH! Email. OOH! Webcomics. What do you mean, class is over?" However, come studying time, I do one of two things: rewrite notes in a separate notebook or type them. Complete crapshoot which I'll choose.

My notebook of choice is the same for anything - single subject spiral bound, not particularly organized. Chaos = life. (I prefer red for "predominantly fiction" and black or dark blue for "predominantly classes")
