I found this really interesting article interviewing an employee at AMD's Mac graphics driver devision. It is about a month old so many of you might have already read it, but it was new to me. It's part of a two part interview, and the second hasn't been released yet. Some topics discussed are "AMD's relationship with Apple and Mac game developers, the transition to Apple's new Lion OS, and the design of graphics card and drivers." Enjoy!
