I am not a casual user. I have literally written the book on Apple development (taking over the Learning Cocoa with Objective-C series, which Apple themselves used to write, for O’Reilly Media, and then 20+ books following that). I help run the longest-running Apple developer event not run by Apple themselves, /dev/world. I have effectively been an evangelist for this company’s technology for my entire professional life. We had an app on the App Store on Day 1 in every sense of the world.
