Celebrate Steam on Mac: free Portal for everybody

That is right, you read the headline. In celebration of Steam launching for the Mac, Valve is giving away a copy of Portal to everyone who installs the service... and that goes for both Windows and Mac. All that you have to do is "purchase" a license on either platform (free of charge through May 24, 2010) and it can be installed on either platform.
What are you waiting for?!?!?!?!
