Just take a look at the simple keyboard entry UI design. It's beyond pathetic. There is a thin blue outline over the next/previous field buttons and that's how they solve the "layered" transparency design problems.
every day I look at iOS 7 UI and I shake my head in disbelief: 5 years of pure iOS UI design down the toilet and this is the best we can get from the same team that brought us the first iPHONE.
I'm in disbelief that they actually let these fake designers work on a flagship operating system.
