When I installed IOS7 in September I had seen dozens of videos on Youtube to get a grasp of what it would look and feel like on my iPhone and iPad I realized that the best feature had been overlooked by most experts. The fact that the black bar at the top of the screen had disappeared and that the color background went all the way to the top. It's incredible how such a small detail can have such a huge impact. It's hard to explain but it feels so much smoother without the black bar. When I try an App that hasn't been updated to fill the screen under IOS7 I feels so inferior now that I'm used to the new Interface.
