iOS 7 is a fairly significant change from its predecessors looks wise, but many of the functional elements of the OS are still the same. For instance, the initial setup wizard looks different, but the basic premise and much of the options and settings are much the same as they were on previous iterations of iOS. Check inside, as I walk you through the initial first boot setup process on video.
Did you notice how much thinner the new loading bar is on initial boot? I think the best way to describe the experience is “familiar, yet different.” What do you think about it?
