I prefer a keyboard, myself

. Voice recognition would be nice, but only if it's accurate. Given only your two choices though, I'd take a pencil. I'm one of those people who will write something down, not like how it looks/sounds, and go back and change it five or ten minutes later. Sometimes multiple times. Besides, my hand sometimes gets ahead of my brain, and I end up writing something that makes absolutely no sense

. Times like these deffinitely call for an eraser.
