Original Mac GUI Artist Susan Kare on iOS 7

Quoted in the Ars Technica article:

Generally a good direction—am a fan of simple, meaningful symbols that fill a space, such as Music and Weather. It's better—more iconic, less illustrative.

I generally agree with the idea that icons should be……well, iconic, not illustrations. So, the trend is good, but the current iteration is obviously pretty rough. I expect they will be refined significantly before iOS 7's official release.
