I had a similar experience with replaceable batteries (1) expensive on the one hand, but at the same time (2) unavailable. I think batteries are the main consumable of a phone. It seems to me there should be an after-market of smaller batteries, and a set of universal power adapters (like you get with power supplies), and shims to fit it securely within the phone. But I haven't seen this, so either people prefer to upgrade (demand) or manufacturers successfully made it too hard (supply).
