The fact that it appears alien to the people you mention is probably due more to having some sort of mental block against exploring computers than to computers being actually alien to them. My mother, for instance, had for the longest time an aversion to trying stuff out on a computer for fear of damaging it. She only started getting it when I gave her an old laptop and assured her that it was ok if she totally junked it. She would still have her desktop and I no longer needed that box. Now she's happily discovering and playing games on Facebook and wasn't even fazed by the recent change in the UI. :)
