I remember being blown away seeing expensive debugging software providing a debugging interface on a second, monochrome monitor. It's hard to bring across how "1 computer : 1 monitor" seemed like such a strong relation inherent to home computers, that seeing a multi-monitor configuration was sort of mind bending. It's two screens, but the same computer, how can that be?[1] That feeling continued on when I had my own, first two monitor setup many years later. Nowadays, it's of course all very mundane.
