a better bet would be the treo 680 or 650 both sold at cingular. I wouldn't listen to what the cingular people have to say about equipment for med school as they probably have no idea about the type of medical software that is available for these smartphones.
I personally do not like the windows platform for PDAs, but to be fair you might, so go to one of the stores and check both of them out. also do a search here about which to buy, it's been discussed ad nauseum.
congrats on your acceptance!
