It's not sarcasm and it's not a joke. It's being an starfish and trying to pick a fight. Leave this thread and let the good people discuss steambox without you as an annoyance.
It is a joke, if you cannot understand it as one you sure have proven your stupidity/disability to understand humor as simple as it may be. Why would anyone fight over whether or not is Steambox a loving rip-off from Gamecube? There is no way that would make any sense in a million years. Its like saying that the Xbox Kinect is a rip-off from Playstation eye toy.
Aside from that, I wonder what the controller looks like, or will the Steambox have a controller at all. What would the game boxes look like? Most importantly, what will happen to the PC steam? I hope that the Steam Box isn't a simple box for streaming Steam games with Big Picture from your computer on a TV. The most revolutionary thing to pop out from gaming consoles would be a built in capture card and as we all know Valve is a nest of geniuses, we will probably (Hopefully) see this in the final product. Since the idea of Big Picture was to take the Internet communities and move them on a TV screen in your living room with easy access, i do believe Steam Box is going to expand on that feature. Hopefully Steam will improve on their web browser though, as we all know it is slower than Internet Explorer.
