How did you feel about green felt? Wood bookshelves? Stitched leather? I hope the answer is “not great,” because they’re all gone in iOS 7. Instead they’ve been replaced with a new cleaner design that’s largely about simple lines and icons. While there are elements reminiscent of Microsoft’s recent Windows Phone design, iOS 7 clearly has its own distinct style. These aren’t just subtle enhancements either; they permeate every bit of the interface.
