The issue is that live demos require INSANE amounts of prep.

You have to go over it. Then you go over it again. Then you go over it again with a stopwatch. Then you go over it again. Then you kill the network and go over it again. Then you go over it again with a stopwatch. Then you go over it with a friend with a stopwatch. Then you go over it again. Then you go over it with a friend but you use the stopwatch with no network. Then you go over it again. Repeat until you feel like you're in Groundhog Day. Then go over it one more time.

By the time you give the demo in front of people, you should be so damn bored with giving it that the only reason you want to give the talk is to see the audience reaction.

And then Windows 95 BSODs and gains more and better publicity than if the show had gone smoothly.
