For me, I've found its / it's is a class of mistake that I never made when writing by hand, however, now that I type almost everything, and have a decent typing speed, I just sort of get whichever one comes out. This happens in a number of other cases (their, they're there). If I'm typing at a stream of consciousness speed I start making all kinds of rudimentary mistakes from what I can only assume is a corrupted mental lookup table :)
