There's nothing inherently wrong with SteamOS IMO. The problem is having a high performance gaming PC without a Windows installation.
60FPS when paired with the latest reprojection techniques (up to 120Hz) is perfectly fine. Oculus even downgraded their minimum requirements to
45FPS when they enabled asynchronous timewarp.
Dual render windows at 60FPS each is pretty great IMO. I can't really notice any difference between native 90 FPS and 60 FPS + reprojection.
Yet all Steam Machines cost way more than the sum of their components if purchased separately, with some models even getting a worse cost/performance than an identical version sold with windows by the same manufacturer. (e.g. Alienware Steam Machine vs. Alienware Alpha R2 at launch, or
comparing both versions of the
Syber Elite even today).
Valve does make a lot of money with software distribution and sales, so people expected that a machine with Valve's platform/store pre-installed (and without any real alternative to Steam in Linux) would be somewhat subsidized, plus the fact that they weren't paying for a Windows license would also reflect in the final price. The end result was pretty much the opposite.
I don't know who was elected the Gatekeeper of the "Console" term, but there's a bunch of respected
hardware &
gaming sites calling the Subor Z a console, or at least a Console/PC hybrid.
Is a gamepad-centered shell for windows all that's
needed to call it a console? There's no reason to assume this Mad Box isn't bundling one, just like the Subor Z is expected to be shipping at the moment.
Maybe Microsoft themselves are planning a Xbox dashboard mode for Windows 10.
