Think about it. Doctor's couldn't effectively show medical information to patients on a small little iphone. It's too small. Way too ineffective. But now, with bigger touch screen it will make it awesome. You could so use all those good anatomy apps way more easily now.
That is where the dollars are going to be.
All the hospitals I've been too in the past 2 years here in Vegas all use IBM ThinkPad X61 Tablet PCs for almost everything. They come to the patient's bedside and get info, hand the tablet to the patient (if they can hold it, of course), use the stylus for the signature, can print out documents right there if needed since the cart uses a portable ink jet printer and it's all wirelessly connected.
This stuff is old hat for many of us that are serious about tablets - Apple is 15 years late to the party but since it's "the next big thing" from 'em, it'll sell like mad.
It's just too lackluster, it could honestly be so much more than it is instead of basically making people wait for two more revisions before it really shines.
Sad...
