I (and many other buyers) don't want a user-replaceable battery. I think they look like crap, they make the phone look like crap, and in my history of owning iPhones since day one, I've never had to replace my iPhones battery. I did have one replaced through a warranty extension thing but that was because I was reselling the phone and wanted to give the buyer a perfectly new battery. Otherwise I would have kept the one inside.
