I've been playing around with iOS7 for a few hours and a lot of the issues could be addressed in the next 3 months. Someone should do a redesign like that guy did for the NSA slides[1]. I think the color palette is taking all of the spotlight away from the key technical updates. Even though the updates are features that Android and WinMo users have had for a while, many iOS users are only getting these for the first time. This is a first cut and there is still three months to clean it up.
