I don't know why iOS 7 transitional animations feel slower than those in previous versions of iOS. But they do. The zoom ins, the carousels, the spin-around, these were never instant things. Yet I never felt like I was waiting of iOS to catch up to me as often as I do now. Maybe the leaps forward in iOS 7 make it feel like a more physical place, and make me think I should be able to run, not just walk, through it. It makes me think I should be able to fly.
