Why is he saying PC instead of Windows? The PC can be open even if Microsoft closes Windows even more, and one can install an other OS on it. (Of course, it is only true until hardware makers all limit what you can install on their computers.)
Probably because, as fair as the gaming industry is currently concerned, they may as well be one and the same.
Maybe Steam will start to shift that, and Minecraft certainly already runs on Linux, but right now in the gaming industry "PC" and "Windows" imply the other.
I think because he uses Windows, and wants to keep using it for years to come. I've always liked using Windows; I buy an OEM copy every time I build a new PC.
If we didn't use Windows, we wouldn't care about Win8. But, we'll switch to Linux if Windows doesn't support our hobby anymore.
