Look, it's not without its faults, but iOS makes for a _much_ more approachable device than a 1993-era Mac. My young son cannot read, write, or speak, and I'm amazing at how productive he is on the iPad. For example, without instruction, he's organized his programs into folders, a task that I know he still can't perform on a Mac, complete with all its menus.
Probably the most compelling advancement of iOS is that it has a "home" state. No matter how far you go or how lost you get, you can always press one physical button to get back to a familiar starting point. I didn't realize how big that would be, and how much it would do to make users feel grounded and encourage exploration. For all types of users, I think that's a great advancement.
As for the gestures, there really are some confusing advanced ones, and I'd bet they have very little real-world traction. Happily, tap, swipe, and pinch are pretty much the only ones you need, and most users can pick those up in the first few minutes.
