Honestly I cannot avoid a feel that Apple has lost its sense of taste and iOS UI was redone just because of outside pressure and nobody with enough authority having the final word.
IMHO a fundamental, ground-up revision of the UI was inevitable and indeed widely expected the moment Johnny Ive was put charge of UI design. I can't see him even considering taking on that job without making sure he had as much authority over that revision as he would ever need.
Right now I have absolutely no idea how much I like or dislike the new design. I've been able to do everything (very few things so far to be fair) I wanted to do, and encountered some small frustrations and nice surprises. I'll see how I feel in a week or two.
How long have you been using iOS 7 for?
