That's the first cloud computing service right? I've been reading about the concept for some time now. I think it's awesome, but I'm not sure how well it will actually work since we're in the very early stages of this sort of thing.
Although, I also don't like it. If cloud computing takes off, you won't actually own any games anymore, you'd buy them, play them, and as soon as you stop paying the subscription, the games you paid for aren't accessible anymore.
I don't know, sometimes I fantasize about quitting work forever and just play all the games I collected, never buy anything new again. You couldn't really do that if you didn't have physical copies of the games, also this could bring about the slow demise of consoles.
From what I understand though, you could basically equip a PC from the early 90's with a good internet connection and play the newest game with the best graphics, and that's pretty cool.
