Steam for Mac?

Steam is a content delivery system made by the videogame company Valve. Valve has been responsible for some of the most popular PC games in recent memory: the Half-Life series, Portal, Team Fortress 2, Left 4 Dead. Up until now, their primary method for distributing the games, as well as the games themselves, has been Windows only. However, Valve has as good as confirmed recently that they will be bringing Steam and their games to the Mac with a series of 6 images featuring Valve characters in parodies of Mac advertisements. They released one image each to a number of online news outlets, along with a subtle suggestion that there were other images to be found. Not only is it a cool ad campaign, but it draws in iconic Mac advertisements from throughout Apple's lifetime - very cool, Valve! The announcement will probably coincide with the Game Developer's Conference next week, a traditional time for companies to break big news. Personally, I can't wait. The last piece of the current (incredibly good) Half-Life story arc is due to come out sometime soonish hopefully; Valve hasn't been very clear. I'd love to be able to play it natively on my computer, so fingers crossed!
