NFC is going to be pushed heavily and will be supported by all the big players...that's not a small deal. In a couple years we won't be swiping debit cards, just placing our phones up to some reader.
And it will have LTE...that's a big deal if you have coverage.
But, and I'm sorry I keep harping on it, the phone will not be a modern sized smartphone! Apple could make one, but they're not for some reason....my guess is they want a big difference between iPad mini and the iPhone. The latest flagship phones from competitors are still well below the size of paperback book, but they're in the same league. If I can read a book comfortably on my phone (as you can with the new large phones) the tablet might not be necessary.
All those things are cool and I get it about the screen I do. For me though I'm willing to give this phone a chance to see if I get use to it. I think this next phone coming up will have something no other phone offers something like haptic touch technology. I really believe that will be in the next phone. From what I've read and seen videos of it will be a game changer. I think that they will reveal why they chose the dimensions for the phone there will be a reason connected to haptic touch. My prediction.
