I find typing perfectly adequate for remembering things - in school if I was copying out notes I did just as well typing as handwritten, and could do it faster (and so get more repetition in) on a computer. Both blew away just reading or listening passively. However, for brainstorming or planning, which is a lot of what this article is talking about, the unbounded spatial component of paper (or a drawing app with stylus) is much better for me than the constrained nature of a word processor. Something like graphviz isn't bad for certain types of things, but anything that relies on mouse-based selection and dragging of things breaks my flow in a way that jotting a new note off to the edge of an open paper doesn't.
