This, of course, was a long time ago. My guess is that today this would be the case for any computer user, Windows or MacOS. At the time this was simply hilarious.
In terms of iOS, the overloading of buttons and gestures makes for a situation where most users don't use any of that stuff. The simplest example I have of this is using the volume switch to take a picture, nobody does not. I know about it and never do it. In fact, when I do it is because I pressed it by accident and end-up unintentionally taking a picture or more.
I have another example that is unrelated to computers. We have these dimming light switches in several areas of our home. If you want to turn on the lights to the pre-established dimming level you single-click the switch. If, on the other hand, you want to go to full intensity, you double-click them. Despite having explained this, everyone uses the little tiny dimming lever on the side of the large push-button plate to go up to full intensity. And visitors, of course, have no clue because the feature isn't discoverable except for a fortuitous accident.
Progress isn't without side effects I guess.
