I disagree completely.. Its one of the best arguments to keep USB ports, as there is no way to do factory restore or any kind of recovery with out plugging in to iTunes, keep an older laptop for this function is just plain ridicules..
What if you do have just that laptop and you need to do a full restore (your phone has iTunes logo on it) what are you supposed to do ? Go out to the store and buy a dongle ? Order it online and wait ? Removing USB ports while your other flagship devices are shipping with USB cables is just crazy ! Not even including a dongle to at least allow that is a slap in the face...
I`m really not understanding what is going on at Apple this days... They do things like this time to time, but not allowing 2 of there flagship devices to be connected together is not like them at all... I really do miss Steve Jobs, this would not be if he was around, no way we would need 4 different adapters to accomplish simple tasks....
I waited 4 years for this refresh only to want to jump ship now.... I guess back to hackintoshes it is...
Haven't read through all the comments yet, but you can back your phone up to iCloud. I don't have a personal laptop anymore, but can still do a full restore on my phone.
