My first two steps into the dark side ...

I just bought two books about programming Mac OSX (which I refer to as "O-S-X" rather than "O-S-TEN" -- because it's fun).

• Beginning Mac OSX Programming (for a quick getting-up-to-speed read)
• Advanced Mac OS X Programming (for information that will likely be more relevant to the iPhone, i.e. Unix-BSD programming tips)

I'd love to get an iPhone specific book and/or SDK soon ... Apple, are you listening?
