In later years, I would learn more about how Steve prepared for these big-splash product announcements. Three weeks or a month before the keynote itself, Steve would start rehearsing with portions of his slide deck in some venue at Apple, often in Town Hall, the auditorium on the Infinite Loop campus. Slowly, day by day, he would build the show by stepping through it as he wanted to present it at the keynote. This was one of Steve’s great secrets of success as a presenter. He practiced. A lot. He went over and over the material until he had the presentation honed, and he knew it cold.
