The thing that amazes me about Jobs is how he could present in such a way that it seemed so off-the-cuff and at the same time so polished. Anyone who has had to do presentations like these can learn a lot from watching him at work.
In the NeXT video, for example, he's very good at tying everything together into a cohesive whole, and speaking to his audience in terms they'll understand. He uses practically no filler words ("uh", "um", "basically", etc.).
Here's another presentation he did in 1980 that shows he had these skills almost from the very beginning:
I think an advantage he had was time. Bill Gates does similarly well on his presentations from that era.
Unfortunately we don't have the chance to do 35 minutes presentations anymore. Now everyone has to squeeze their pitch into 30 seconds information-free commercials :)
How do you get meaningful ideas across if no one has the time to listen? Only the most superficial ideas can be put across in an elevator pitch.
