I am disappoint.
Siri looks very cool but I can't see myself using it that much, and I use my iPhone for simple games not huge epic things (Infinity Blade works very well on the iPad but not so good on the iPhone IMHO). A better camera is a nice touch but it's perfectly acceptable as it is and I have my D90 for proper photos. I don't need any more space at all either, so the 64GB is pointless for me.
I so wanted this to be amazing, and it's really not. It's still better than any Android phone that I can see, but it's not enough to make me rush out and get it.
