aside from the games thing though, within that massive app catalog there are bound to be a few that really appeal to each individual user. it's not that everyone's going to use all of the apps, it's that there are likely to be a few really serious apps that are available only on the iphone that the individual customer won't want to give up, or at least would expect to have on an alternative platform.

i can only talk about what i use it for, but there's an incredible japanese-english dictionary and 3D graphing calculator that i use all of the time, and neither of them are on any of the other platforms. that would be the bare minimum for me to consider switching, and i think there are probably a lot of others in similar situations.
