Yes, I am a developer as well and have been using iOS 7 on my personal device for about a month now. I am only speaking about the UI - sorry I didn't make that clear. I prefer the previous UI. Easier to read and navigate and buttons/controls stand out more, which is important for a small touchscreen device. Control center is a small improvement, but iOS 7 UI is a step backwards for overall usability. That's just my opinion after 1 month of heavy use.
