I wasn’t impressed at first when looking at the livescribe smart pen hardware specs (although impressive, that’s in a way just another smart pen), but the demos made the coin drop: synchronizing audio with smart paper notes sounds like the killer app for smart pens, and that pen seems to do it right. Can’t wait to try it!

Nice, but talk about lock-in… you need to use their *paper*!
http://www.livescribe.com/support/kb/?View=entry&EntryID=104 says “We will also enable customers to print Livescribe dot paper for free…we estimate that it will be a few more months…” so there’s hope!
I’ve seen the demos at JavaOne and it was really impressive. I really regret not to have bought one there.
@Gianugo They have announced that the paper will be freely available within a few months.
