I type rather quickly (fast enough that I can type faster than I can compose), but still prefer pen and paper when reasoning. It's because the pen and paper mixes diagramming, text, and non-linear note taking in a completely different way. There's just no good typing analog to drawing a box around something, and then an arrow to another boxed item with some notes next to the line about the relationship. There's no good typing analog to writing notes off to the side, and then notes on those notes, and arrows between them. (There are okay mouse analogs, but constantly shifting my hands from keyboard to mouse is fairly annoying; much more so than just writing.) It's not that I can get a computer to do those things with various editors, but rather, that typing in the instructions to do them is fundamentally mentally different than actually doing the motions of the boxes and arrows by hand. (My pet theory is that my brain is using information about the tactile movements to store relationship information in a way that it doesn't understand for digital documents, but I am not a psychologist.) This difference has nothing to do with typing speed, but rather, the nature of the input device you're using.
