Apple tends to yank apps over duplicate functionality, use of private APIs and those that look and feel very much like stock iOS programs. So it goes without saying I was surprised to learn that the company approved Track 8, a $1.99 music player program by Ender Labs. That Apple greenlighted an app resembling a rival platform's UI rather than flaltly reject it is news in and of itself, you'll admit.
Maybe the company just doesn't care because Windows Phone is failing? Be that as it may, people will wonder if a Metro-style interface makes sense on iOS...
