I'd like to know about the 'different study skills' that are needed (#2, above).
Just got my Kindle DX and am loving it. I have lots of PDFs, so it's going to be a wonderful, but I am thinking that on books and articles that are ones I want a lot of notes on will need more than the built-in highlight and notetaking features.
Back to old-school notes on index cards or in notebooks?
(Like rgeorg, I can't access the article.)
