Note: 4 years later, during WWDC, I interviewed him again just after the launch of Swift, the language. Check it out.

Needless to say Aaron is some kind of "Steve" for us Developers. For most of us (especially the "younger" ones), he was one of the first introduction to Cocoa & Objective C. Furthermore, I was amazed how nice & gentle he is. Somehow I range this interview with the one I did with Woz.
