No texture. No background. No effect. No color. Just blue on white. That's it. 2D symbols, 2D apps, blank backgrounds.
I don't call that a "design". I bet a first year student can make something like that. Now the iOS 6, THAT'S desgin
Well, for good design all of that (textures, 3D etc.) isn't really mandatory. But the more you reduce it to the essentials, the harder it gets to make it look nice/attractive/aestetic. Apple has gone for the hard way with the radical reduction and -imo- didn't hit the sweet spot at their first try.
I hope that they don't think that this is "good enough" because they are usually known for striing for perfection. When people state things like "I don't mind the icons", I don't think that this is a good sign. I am excited and worried at the same time.
