This is just a great read, especially if you are interested in the history of the iPhone and of Apple in general. One tiny highlight:

I was in the audience on that January day [that the iPhone was launched] in early 2007 and when I walked in that morning I didn’t know what the product would be called. We called it “Purple,” which was the code name for the phone, and it was a surprise.

The fact that the team was able to keep the iPhone name a secret until the reveal is amazing to me. Certainly, that name would have been a reasonable guess, given that the iPod existed and this was a phone extension of the iPod. But it would have been speculation, not a leak, and it was known at the time that the iPhone name was owned by another company.
