You have to include that in the price though. Most people don't have pc's capable of running it as very low %'s of people need a 980+. And that performance curve is likely to stay there for quite a few years as people try to eek more and more out of it, so I think it'll mirror game requirements.

I would also ask, what's the market penetration of a $600 smart phone that you can take everywhere and do tons and tons of useful things with? No where near facebook's total penetration. Sure they're becoming more and more ubiquitus but remember that most people don't have a need for a upper end gaming pc and convincing them that they have to have it so they can virtual-skype with their friends from only one room in their house makes it seem a lot like the original telephone for quite a while. Expensive, and tied to a single place.

Don't get me wrong, it's SUPER COOL to demo (I went onsite at valve).
