The iPhone 5 is better than the 4S in every aspect. It has a larger and improved display, a thinner and lighter case, and a faster CPU and GPU, but we would have liked to see more innovation. Manufacturers of Android phones frequently add new features, and in that regard iOS is treading water a little bit. The OS was revolutionary back in 2007 and ahead of its time. Now Android has caught up, and perhaps even surpassed iOS in some ways.
