I'm typing this on a smartphone. I don't conciously think of it as my "magic pane of glass" like the cliched Roman might but what's actually going on when I tap this screen is as much a mystery to me as it would be to them, at least beyond a few high-level concepts which it also wouldn't take all that much time to explain.
