> A photo gallery in a smartphone is extremely dull in comparison, and that's why they can learn to use it immediately. I think the reason they can learn to use it immediately is that it's super-simple to learn - tap and swipe, and not very many of those gestures at that. Phone interfaces now are designed to be used by /anyone/ - and that means keeping them simple enough that it can be learned quickly by a child.
