i typed, and i am not a super fast typer. i just know that when i do notes, i usually make a mistake or two, list things in the wrong oredr, or whatever. so, with the comp, you can cut, paste, delete, etc, without affecting your space limit. also, a big concern was legibility.
what i did was to basically do two practice cases out of first aid. i used the form in FA to write my note on one, and the form on the USMLE website to type the other. i timed it, checked out how they came out, and just decided that typing was the way to go. then i practiced typing them. i think it worked out far better for me. and, remember, you can do both, just not on the same patient. so, if you hand is getting tired, type a couple. or type ones that you get out early on. mix it up a bit!
best of luck.
