Compare what happened with our shell windows with what happened with our "smart" phones in the last 20 years and you'll get some inkling of what I think we're missing. It's not that we should program the way we use iPhones, but that there are fields where user interface work has made a real different recently. Not so in programming, though. We're missing out.
But I'm a grumpy old man and getting far off topic. Warren should cry, "enough!".
