OK, you don't have to hide it, but there still needs to be some kind of guide about how games will play on your Steam Machine.
This is not a big deal right now, but what about in, say, 6 years? You have an original Steam Machine and a new game JUST came out. It doesn't run on your Steam Machine because yours doesn't have a Whatsit Quantum Coprocessor. Shouldn't the Steam UI, you know, let you know that before you go about buying and downloading that 30GB game??
And I don't want tiers, either, but Valve did say they'd have something to say about this; I'm simply speculating about what it could be.
