Presentation Zen: Even legendary jazz artist and master performer, Wynton Marsalis, couldn’t help but be impressed by Jobs’ presentation skills. Just seconds before Marsalis raised his trumpet to play, he paused and said (without a direct mic)…”That was a great presentation.” The audience laughed at what was clearly a spontaneous gesture. Marsalis and his band were the “encore” to Steve Jobs’ special presentation and media event in San Jose, California yesterday (October 12). And Marsalis was right: It was a great presentation…as usual.
