iOS 7 obviously took a lot of inspiration from other mobile operating systems, but the one thing it has that those platforms don’t is massive cultural influence. A year from now, “flat design” will be a household concept, and everyone will be tripping over themselves to mimic it. A lot of them will fail, but at least they’ll be (inadvertently) doing the world a service by trying to simplify things.
What’s the point anyway of trying to complicate something just for the sake of complicating it? We live in a world with enough noise and clutter already. I hope iOS 7 can help shift the aesthetics of our culture toward clarity and put a stake in the heart of over-designed crap.
