One big moment was when Steve announced that Apple was going to give an iPhone to every Apple employee. The excitement that was already present went up tenfold as everyone leapt out of their seats into a huge standing ovation that lasted quite a while. The cheers and yelling got even louder when Steve said that it would be the (larger) 8 GB capacity iPhone we would all be getting.
One former Apple employee documents the day before the first iPhone shipped to the world. He describes a Comm meeting on June 28, 2007 at which Steve Jobs said “Today is the day to reflect on what we’ve done and what is going to happen.” Very interesting and insightful read.
