Apple's Steve Jobs is such an icon that when he came on stage today wearing a black buttoned-down shirt instead of his traditional black turtleneck, the audience tittered.

"He's wearing a button-down!" one analyst whispered. I can't imagine anyone reacting that way to Steve Ballmer's wardrobe.

One special guest at the event went largely unnoticed by the reporters in attendance. Steve Wozniak, who co-founded Apple Computer with Jobs, rode up to the building in his Segway and helmet and barely drew any glances. He didn't speak on stage, and left soon afterward.

The only person Jobs invited to the stage was Bob Iger, the chief executive of The Walt Disney Co.

"The consumer has indeed spoken, because the success of TV programs on this platform is enormous," Iger said about Apple's iTunes program.

For a media and analyst event, Jobs' speech elicited a surprising number of oohs and wows from the audience. Either Apple seeded the group with its own enthusiastic plants or some people checked their objectivity at the door.
