I'm glad that works for you, but I'm with the other old-fashioned types. For me, dragging together materials generated by others into a pastiche, no matter how brilliant, does not impart understanding in the same way that having to understand things well enough to write short notes and diagrams does.
When I was in college and grad school, all my notes were pencil and paper. Good notes aren't textbooks, they're pointers into the memory structures you're building around a topic.
My work now doesn't involve much diagramming, so taking notes on an 11" Air works great. But anytime diagramming is required, I go over to the nearest laser printer and grab some paper out of the drawer.
