I guess some of those could be handled by going into an apple store, but I'd still be a bit peeved if they removed the lifeline to my phone as a cost cutting measure.
I'm no expert of course but areas like the south in the United States are still stuck on DSL lines and even older technology.
I would think that this would be reasoning for not doing that yet.
Then again, if they do go towards a totally wireless phone, I guess it would only be sensible to just ditch the lightning port entirely. and have a fully sealed case.
Still, I'd be pretty happy to have a stand-alone sync/management app; right now I use iTunes as an staging ground just to make sure that whatever goes on the phone looks right in iTunes first (correct tagging, correct album artwork). I don't mind it in this function, but if I could I would do away with it.
If Apple provided a documented set of APIs to allow me to setup my own server then this would make sense. As it is, I see no reason why apple should hold my backups on their systems, why they should have any involvement with my syncing of data to my phone.
