I looked at the OP article and it seems too fetishistic for my tastes. What happened to ordinary yellow legal pads, or spiral bound school notebooks? For daily casual jottings, I used to use paperbound pocket notebooks, but they kept falling apart with use. Now I just carry a folded up piece of 8.5"x11" printer paper and transcribe any content needing preservation to a computer when I get around to it. The rest is ephemeral and I can throw away the paper when it gets full. Lately I read on Stephen Wolfram's blog that he does the same thing I do. I don't know if that's a good sign or a bad one.

Heh.
a) take lecture notes in class
b) as soon as possible after the class, refine those lecture notes by combining it with references from the textbook and other readings or handouts.
c) visit your instructor during office hours to clear up things you weren't able to during (b)
Unfortunately the advice didn't come with any time management tips so I was almost never able to follow it. The worst of it was revisiting my unrefined notes 3-4 days after I took them. They often seemed to read like gibberish, especially if I had not been studying the reading material in the meantime.
If anything, computer notes distracted me from the lecture. But writing out summaries from slides after the lecture was invaluable, even if I never looked at those summaries again.
