Portal is the first of the games to be released for the Mac, and on top of that, it's free! This deal is also available for PC users, meaning that if you own a computer, you can get Portal free of charge. This only lasts until May 24th, though. After that, Portal will go back to its normal price.
And in regards of Portal, after the 24th, if we install it now, will the game stop working?
EDIT: Like a demo?

Nope. If you download it now, it's just as if you bought it. The full game, no catch. May 24th is just the deadline. So long as you get it now, it's yours forever.
