Is it not possible that someone, deciding to make a touch phone at about the same time would look at: What is a good physical size for the screen. What is the kind of resolution we can get on a LCD of that size? How many icons can we fit on that screen, which can be easily manipulated by users (there aren't that many options, as you can't fit that many icons on the screen). It seems to me many of these kinds of things fit into into a set of "only one real option", once you've decided (and this might be the 'big copied thing') to have a phone which is just a touch screen + a single button (or 3 on android)).
