I think this is irrelevant.
Valve are open and active in allowing others to use Steamos and I see active cooperation on driver's ui and controls.
Valve are way ,way ahead of everyone else on gamepad compatibility and user configuration ( I found my glasses)
I have a deck, great buy, I wouldn't mind a deck two twice as fast, but I think it's easier and could be better if others worked on hardware too.
Choice is king.
Valve do make good hardware at amazing prices though the base model and another SSD to fit in it can't be beat , even the highest priced one has no pear in its price range in performance term's, so they did good them Valve engineers.
