Fifteen years ago yesterday, Steve Jobs announced the iPhone and had a really good day. Granted back then the “figure out what Apple is making next” business wasn’t nearly so sophisticated, but he was truly able to pull a revolution out of his pocket.

Watching the Keynote again just reminds me how Steve was at the top of his game that day. The voice infections and the use of pauses and questions to create tension and then the release of that tension are all worthy of study if you speak in front of groups.

Every time I watch this Keynote, I also think of the Apple engineers in the audience that were doing shots of Scotch as their apps were demoed successfully (and didn’t crash). I wish we had video of that.

It also helps that the product he introduced was about to turn the world upside down.
