I like watching that 1996 WebObjects presentation [0] just to see how technically detailed Jobs could get, in a time before Apple could just dominate the consumer attention span with the slick, adjective-heavy presentations they have today. He's taking questions from the audience, people are walking around in the middle of the presentation. He may not have been a programmer but he knew how to talk about the details, not just talk about the big and beautiful ideas.
