Let's compare this to the changes in Samsung Galaxy S3 compared to the S2:
- Slightly larger screen
- Faster CPU
- Improved camera
- Added LTE
- Faster Wifi
- Added NFC
- Added a couple of sensors
- Better battery life
- Heavier
Not a whole lot different from the iPhone changelist, and I bet it's not a whole lot different from any other phone maker's changelist between generations either.
But Samsung didn't deliver any magic in the S3 - and what could Apple have delivered as a super-duper-WOW feature? I cannot think of any technologies out there that they haven't squeezed in there yet and I don't think "wireless charging" is anything to really care about, novelty and "OMG!" factor aside. Adding NFC would have also been just catching up and personally, I cannot see the benefit from NFC and it looks like Apple can't either.
So what is left then? What COULD they have added to floor people? Nuclear reactor? Drones? I cannot think of anything.
