Steam OS will be a failure, like every other reinvention of the wheel, such as Google+. There is no reason to pick it and it's box over the dominating consoles or PC's. None, zero, nada.
I think this is a classic case of 'the wise boss' panicking after hearing a piece of news (Microsoft's Windows intergrated game shop), coming up with an idea to solve the problem and no one having the guts to put some sense into him once the snowball started rolling.
Windows costs a lot of money. Steam OS is free. Both beer and freedom free.

Plus Microsoft could just make this problem go away if they wanted to (proper gaming OS - not a phablet one, stop pulling crap like GFWL to name but two options) but elect not to.
The problem with steam os is the whole lack of directx.
Otherwise it's no more viable than people using Linux already .
DirectX is what ties the games to Microsoft so we'll never get one without the other.
OpenGL will be fine
And the modern games available in opengl are in the vast minority, thus no more viable than a normal Linux distribution .
