I would also love to see the hard numbers on the 5 compared to the 4s.
Cutting straight to the heart of the issue at hand. Apple has built up an enviable fan base over the years but if they don't do something innovative they will lose their fans.
Personally I have seen one of my friends get a iPhone 5 (he is a developer and needs one, he has a S3 as well) and about eight of them move from iPhone to Android. It seems like the only people who still buy iPhones are the people who invested heavily in third party peripherals or apps and the people who don't want to move out of their comfort zones.
Have seen the same trend in my office.
