I know what you were talking about. It just made me think what would it be the perfect gaming PC for somebody like me.
Convenience (AKA laziness) is a big factor for me. I already loathe the rare occasions when I sit down to play a game and the 360 wants to install a dashboard update.
I think a big selling point of the Steambox is to retain that convenience. Turn it on, goes straight to Steam, play your games. If it needs any driver/opengl/directx updated, it gets taken care for you, nothing external you have to deal with/messing up your gaming experience (anti-virus, the chinese hacker flooding your SMB ports, etc). I wanna turn it on, pick a game and play. I want that out of the box, I don't want to put the time to configure a PC like that. I don't really care for "upgradeable" either if it's only $400 and has a 4+ year lifespan/support. Obviously, needs to have the AAA les supported, otherwise it's not worth it.
But then I look at that description, and it's really what we call a console these days.
