This is just ridiculous idea. I would rather they try to sell me teleport technology than this cause it's easier to swallow. And the most ridiculous thing is they couldn't sell cloud computing to corporations for office work, where it actually makes sens, now they are trying to sell it to gamers? I think they take us for retards.
Just think about computing power requirements? Come on even your ISP has "fair usage" in your contract. And the least problem for this to work is your internet connection. This idea is such BS i can't think about it anymore without my head hurting!
