For those unaware, Steam is game company Valve's game distribution software which has been on PC for quite some time. Game titles like Half Life, Modern Warfare, Team Fortress, and Left 4 Dead all run exclusively on Steam and, as of now, don't have Mac OS X versions available. Needless to say, Steam on Mac OS X would represent a huge opportunity for Mac enthusiasts to finally dive head first into gaming.
Turns out
Valve is probably developing Steam for Mac OS X soon. What does this mean? Get a Mac with a good video card. Now.
