I agree with you- that example may not fit everybody's problem. When I switched from a simple phone to a smart phone it was important to me, but now I don't bother (never too far from a charger).

And you are right, of course, in that ios allows most people to do the things they most care about very easily-- that's probably the takeaway. If you do that, then, apparently even if the other stuff is hard, people will probably figure out how to do it when they need it. Somehow.
