Are the two apps I'm aware of that allow you to take either typed or hand written notes, and sync them up with an audio recording of the lecture. Let's say you're going back to your notes for studying, and you find your notes on a specific topic a little confusing, simply click on the note and the app will payback what the professor was saying at that exact moment. It greatly improves the efficiency of studying, and I personally don't see how audio recordings of a lecture can work without that functionality.
Dang, that is pretty useful. Wish we had that kind of stuff when I was in college (our college required computers but I think it was a new requirement and laptops were pretty expensive, hell, PCs were probably still over 1k so you didn't even see many people with laptops.. I don't think I knew anyone with a laptop, laptops at the time were for business people who made a lot of money, not poor college students. It would be really rare to see any student taking notes with a laptop though I did have a friend later in college show me his new PDA thingy (ran some mini version of Windows, I was so jealous of the idea of having a pocket computer. To the point I made sure to get a PDA once I was out of college and had a good paying job. And ever since had some sort of PDA then a smartphone).
