I wouldn't be surprised if a large number of those people would revert back to iOS 6. iOS 7 feels rushed, it's great in some ways, but horrible in other ways.
Edit: Some people don't agree with my comment. I'll make a thread about the flaws in iOS 7's design some day - just for you!
I love the arrogance of these types of comments. People have some minor insight (even if it's their profession) and assume that some break from convention or oversight means that they would have seen it and ensured it had been fixed.
Is iOs7 flawed? Yes. Would it have been better without those flaws? Of course. Is it better than iOS6? Yes. Should it have been held back? Logically, no.
But thanks for your self assumed insight.
