First and foremost, I believe at some point in the past I said I would apologize for my trolling once Steam for Linux became reality, and not just a hobby side thing by someone within Valve. Therefore, Michael, I'm sorry for trolling your forums when you posted about Steam.
I'm also very happy about this situation. I'm setting aside money to buy whatever launch titles there are that interest me in the slightest. L4D and Serious Sam certainly fall within that category.
