Typing and writing long-hand produce different kinds of prose for me. I like to alternate. My typed prose is a bit jerkier, with a higher density of facts or points, while my long-hand prose has a more conversational flow.

And my hands start to ache if I use a ballpoint too long. Ever tried taking 5 hours of notes at a math conference with a crappy ballpoint? And live-texing is fine until you've got more pictures than text...
