I've downloaded the Steam app for my Macbook which is AWESOME.
I hope that it goes smoothly for Mac users like myself. I have a PC for gaming but use the Macbook for video/sound editing.
This will bring games to EVERYONE, except of course Linux. Maybe one day it'll happen.
Hope this forces Apple to make MacBooks with better graphic cards, the one I currently have isn't so hot.
Well it burns my skin though.
