I liked how they reacted to the guy asking questions about Mac Writer. It showed both what the mentality and expectations of software at the time were and what a step forward compared to those Macintosh was.

He first asked if it is possible to center only part of the document instead of the whole document as demoed and then he asked whether select-and-replace worked only for replacing equally lengthy text. Both of those questions were followed by laughter at – what I assume – was the demo that both of that was no problem on the screen.
