What bothers me is that in terms of openness, the iPad is the same as the iPhone, but in terms of form factor, the iPad is essentially a general purpose computer. So it strikes me as a sort of Trojan horse that acculturates users to closed platforms as a viable alternative to open platforms, and not just when it comes to phones (which are closed pretty much across the board). The question we must ask ourselves as computer users is whether the tradeoff in freedom we make to enjoy Apple’s superior user experience is worth it.
