I'm fine with most of the things in iOS 7, icons, etc... is tolerable.
But, there couple of things that, in my opinion, they ruined.
1. Calendar
They absolutely butchered it, how is the new calendar better than the old one?
So much white space, and it's hard to quickly glance at it and acquire information. Also you don't get dots for events anymore. And month view with events underneath it was much better. Calendar is ruined.
2. Spotlight
The new placement of the Spotlight search is better than the old one, but they should've integrated it into the Notification Centre. That way you'd have quick access to it from anywhere, any app.
3. App Switcher
IMO, the new app switcher is terrible! How is better than the old, where you could view 4 apps at the same time and it was more minimalistic.
They could've made it better than just copy from Windows Phone. At least copy from HTC One or Nokia N9.
Or the best solution, IMO, would've been to put the switcher into the Control Centre. And slide left to view the current shortcuts. They could even make it looks like a card view with app thumbnails.
