Livescribe makes smartpens that allow you to record lecture as you take notes. If the lecture is going too quickly for you to keep up or you find your attention wandering, you can go back to any gaps in your notes after class, tap on that area of the paper, and the smart pen will replay the lecture from that exact spot. You have to use special paper with these pens, but you can then transfer your notes (along with the audio file of the lecture) to your computer, laptop, tablet, and/or smart phone.
