I certainly shan't be stumping up £550 for a thumb print scanner over and above my 5. IT'll last me another year until they bring out the next one. IOS 7 will make it feel like a new phone anyway.
I did the pre-order deliver to door option for the 5 and it arrived at my office at 11:30am. When I queued up to buy the iphone 4, I queued from 7am until 11am to get my device and then drove to work late.
I know which I will be doing this time.
