I ran across this image: Seeing them side-by-side, I was surprised how sharp and 3D iOS 6 looked compared to iOS 7. The subtle shadows behind the icons and their captions in iOS 6 really make them jump off the screen, whereas in iOS 7 they blend in and look flat. Now, you may object that this is hardly a fair comparison because in the static iOS 7 image you can't see the parallax effect. But in my experience (been using iOS 7 since beta 1), the parallax effect is subtle at best. (I once turned it off and forgot I had done so. I didn't notice it wasn't there). In actual use, none of stands there wiggling our phones back and forth. We hold them still, in which case, there's no parallax effect to see. I've said before that I like iOS 7 better than iOS 6, and I do. But I think there are a few areas where they've taken a step backward, and I think this is one. I'd like it if they put back the shadows they had in iOS 6.
