"Replaceable battery is moot. Not once in ~10 years of owning cell phones have I ever replaced a battery. Not once. People keep complaining about this but no one will actually use it. If you really need the extra battery buy a case that has a battery, they make them. I too would like to see a micro SD card slot but I just don't see it happening. No one would buy higher capacity models. "
Uh you must have some powerful phone because some phones I used, I loved dearly, but their battery die after a year or two if you talk on it a lot. So to say it's something no one uses and that you 'never replaced the battery', is just like saying your laptop battery doesn't slowly degrade (which is does) and it does need replacement. You probably never replaced a phone battery because you get a new phone all the time, but not everyone can spare another $200+ (retail) for a newer model of an iPhone if you don't use AT&T, or have the time to bring or send the phone to Apple.
And of course no one would buy higher capacity models, because there's microSD.. what would be the point of making so many models? You could buy a 100kb model and use like a 50GB card on it.
