Seems more to me like they're gonna get the ball rolling then rely on 3rd parties making the consoles.

Like they'd rather do what Android did and get their OS on as many different types of hardware possible rather than locking you into buying only their hardware.

That's how it looks to me, anyway.

I love the Steam Deck, but if competition comes along and makes something with better hardware and repairability then we all benefit in the end, and Valve benefits even moreso if that new thing comes with SteamOS.
