Ah, then why bother carrying a phone around with you at all then? What you described is the very essence of a mobile phone.
Don't take this the wrong way, but you need to accept that whatever AAPL gives you is all you need. You don't need push notifications, you don't need A2DP bluetooth stereo, you dont need turn by turn gps, but you do need to give AAPL $0.30 for every DRM track in your library to free it.
