Livescribe is a company that makes a pen that allows you to take notes on specially printed paper and then takes those notes and matches them up with audio that the pen records in the meeting. You can tap on your notes in your notebook and the pen will playback the audio from that point in the meeting.
It is one of the coolest devices I have ever seen and it also integrates with Evernote. You can also buy the MyScript for Livescribe software that does OCR on the notes taken as well.
You can watch all the Livescribe demo videos here.
