Typing! Fast and easy. I don't like to communicate over the internet or whatever by talking, so typing is for such purposes also better

.
And about my lecture notes... sometimes I really can't read anymore what I wrote xD, that's bad

. But for during lectures it's ok
And with talking you can still have misscommunications (because of the intonation of ones sentence and such

), so that wouldn't even be a pro any more
