It depends which users you're talking about. I'd guess (based on the lead-user theories of Yochai Benkler) that a ridiculous of amount of innovation is going to come out of Android, because of it's toolkit nature combined with the type of people who would buy a phone just to make it do something that currently can't be done, who have no other suitable platform.<p>We've already seen a wave of innovation from "users" building apps for iPhone, Android just continues and expands this into the next level down.
