As I said in a comment above, for most people, taking notes by hand (during class, a meeting, etc.) is superior for understanding and retention. I take all such notes and reading notes by hand and then type them up if they are something I want to save and access later.

I do most of my writing of academic articles and the little fic I now write on the computer. I might do some of the writing by hand if I'm like in a meeting and bored or something. But the majority of the composing will happen on the computer. With academic writing, I need to consult files of notes, use quotes I've typed out--it's just easier to have all of that there.
