Steam, and Starcraft II are all I need for my macbook pro, I deleted my bootcamp partition today, and each wednesday I will be able to install more and more source games. I still have my quad core monster PC for real gaming, but steam on mac has opened so many doors for mac gaming. I was shocked when I saw that 67 games are available on day one! and free portal! I almost bought it for $20 last night! torchlight and portal should keep me busy for the next week. Who else feels like they can finally use OS X exclusively on their macs?
