I did an experimental stint of turning in problem sets in TeX and found it to be very time consuming, though part of the exercise was to write up the solutions carefully and that took time too. I don't think I could possibly take notes in class that way. Also, typing in class would bother people, I expect. One of my professors told me that the best way to do notes was write down normal quick ones in class, but then at home, rewrite the notes in complete sentences including the stuff you remember from the lecture that you didn't originally write down. He said this was a big help in absorbing and retaining the material. It sounded like a good idea, though I was too disorganized to actually try it.
