Its the one thing that holds me back from ever getting an iPhone. I love my Touch, and would love to cut down on my devices (I currently use a Black Berry Tour). The biggest problem is no replacable battery. 1. I would always be afraid to watch video, or listen to too much music for fear of loosing my phone while it had to re-charge. 2. It kinda feels like an rip off. Now Apple is pretty much assured that you have to replace your iPhone every 2 years or so since the battery will eventually die. I like the fact that I always have an extra battery for my Black Berry on me, and will be able to use it for years to come, if I should choose. Sometimes Apple drives me crazy.
