Kelsey Campbell-Dollaghan, writing for Gizmodo, presents a nice take on iOS 7’s design:
The predicted rebirth Susan Kare’s original black-and-white OS design, it ain’t. Actually, let’s just ban using the term “flat” altogether for this post. The iOS 7 we met today was full of what Jony Ive called “new types of depth.” Alongside a poppy, neon-and-pastel color scheme, the icons, apps, and homescreen of iOS 7 are full of layering and dimensionality. There are also entirely new types of animation: from a screen that uses the accelerometer to adjust in parallax, to beautiful new animated weather icons.
