I keep thinking about a console, but then I think that the PS3 and Xbox are horribly outdated and due for a massive refresh any time now. And that's the problem with consoles (and their benefit). They are always behind computer gaming on the one hand and usually lack typical PC controls that are good for some games (like a mouse), but on the other hand you usually know the game will run reasonably well and at least no worse on your console than anyone else's since they're tested on the same basic machines (whereas computer gaming can be all over the place with different hardware and CPU/GPUs and even operating systems).
Exactly, which is why I am awfully curious about Valve's SteamBox.
