Definitely not what I'd call "the best thing to happen to iPhone since iPhone". A bunch of nice improvements, but that's pretty much it. And -100 points for changing connector and not using a micro USB like everybody else.
It's the second underwhelming iPhone release in a row, and the aggressive pricing seems to reflect this; I wonder if this is an effect of the lack of Steve Jobs at the helm or it's just that there's only so much you can improve in a smartphone these days.
I hate micro USB, being small and short it makes it easier to trash the phone, every time you get the orientation of the connector wrong, you can scratch the phone.
