I dunno... being an iPhone user for 2 years now I'm fast on the keyboard -- really fast and accurate. I also own a BB for work and I find typing on it to be quite a chore these days. I think there will come a time when people really have to re-evaluate the bad rap the iPhone keyboard gets. I admit it's probably not for everyone but lots of iPhone users are very quick and accurate with it. I suspect humans can adapt to almost any type of input/control system with enough practice.
