I think that at least Apple could put the Xcode binary files onto a CDN inside China. I'm trying to download Xcode 7.0 from the App Store today, and it's still hanging after a few hours.

The "Send" text is gray because the input box is empty. When you typed in something, it will turn blue. Still not as intuitive as a button though.

It's exactly the same as in iOS 6. There've always been two different call screens since the first release of iOS. One is shown when your phone is locked, where you need to slide to answer and push the power button twice to reject. Another one is shown when your phone is not locked, where you have an answer button and a reject button. The screenshot causes the confusion because it is comparing the second call screen on iOS 6 with the first call screen on iOS 7.
This is a typical driving school. The curved tracks are not long enough to train police or test cars. You can only drive through it very slowly. And you can see there're parallel parking stains as well.
