Basically Microsoft presents this "incredible" product, and then says in the same breath: "Oops, not for your current setup. Maybe you should consider buying a new PC?"
My largest showstoppers with Linux is the lack of DRM support, the lack of "just works" installs, no Parsec (I've tried Moonlight/Sunshine many, many, many times, it never works for me), and ... this one little thing ...
I would use Linux more if either Virtual Desktop or Steam Link worked in Linux. As it stands, neither work, and current implementations of VR in Linux are still alpha / experimental beyond Index / SteamVR direct tethering, not an option for someone that has a cheap standalone headset.
Parsec is like Moonlight / Sunshine in that it video streams your desktop for remote access. It is very low latency and lets you even game remotely. I've used it to remotely video edit and also test things, mainly to control my beefy desktop from my laptop in a remote location. The difference between Moonlight and Parsec is, Parsec's 1000x less painful to setup, especially when connecting from across the internet.
