My notes in college followed this route. I would take notes during lecture with pen on paper - less distracting, less likely to go wrong, lighter, and battery life was not a concern. (Today, I would likely take notes with a stylus on a tablet.) When I sat down to revise my notes, part of that revision was to type them up in Emacs with org-mode, using embedded LaTeX for any notation that was not natively supported in org-mode. I would frequently already have typed notes from my readings, and I could integrate the lecture notes with these. I would render to PDF and print these out for further study away from the computer. Part of the reason for this is that I found having access to the Internet and my collection of computer games was distracting when I was trying to study. Being able to print out the notes, share them with friends, study without having to haul around a laptop, find power, or navigate with a keyboard in the silent study floor of the library was important.
