Oh same here, but Jobs's reputation was for... not suffering fools gladly. Based on that reputation, I expected him to come down on the guy like a hammer.
Jobs was a showman. And a leader. He was hard on fools at close range, mostly behind closed doors. He had a really high bar of excellence. But punching down at someone in the audience, whether a fan or an employee, that isn't anything he was ever really known for.
