Pixel Envy has published a very in-depth, design oriented review of iOS 7.
iOS 7 is Aqua. It’s a fresh start, using new technologies which weren’t available nor practical in 2007. It’s going to change over the course of the next several years. But its foundations have been laid, and they are very strong.
It’s a truly sublime experience which manages to preserve the familiar aspects of iOS while providing a brand new look and feel. The redesign makes the entire user experience feel brighter and more alive. It’s not just a bit of trite marketing: updating to iOS 7 really does feel like getting a brand new phone. I have thoroughly enjoyed the time I’ve spent with it so far, and I’m excited to see where it goes in the future.
Right now, though? It’s spectacular.
