As I said earlier, the loudest voices are always the unhappiest ones but they are often always also the minority.
I don't see why people are taking a tantrum over an OS update that you have a choice to upgrade to or not. I don't buy that people, especially some in this thread, did not know about the UI redesign in iOS 7.
I refuse to believe you people don't read any other tech sites, use any social sites, or have friends or family with iPhones (every family has a tech nerd who's plugged in to all the news. I am my family's!

).
To claim ignorance on a level that suggests Apple "tricked you" with iOS 7 is ridiculous. And to top it all off, there's details of what iOS 7 contains within the opening page of the update description. If you didn't read it and blindly pressed update than that is your fault, not Apple.
