I have been using a Boogie Board Sync for a couple of years (the original, haven't tried the latest). It syncs with dropbox and allows automated filing into one of four types with a stroke of the stylus. Best note taking implement I've ever used - and I used paper for years. This replaced it. I use it to teach my children new ideas, note everything down, test theories. Give it a shot.
