I'm personally quite hyped to see the first commercially available Linux-based standalone VR headset announced. This thing is quite a bit lighter than any of the existing "cram a computer in" solutions.
Strictly speaking the mobile Oculus/Meta Go/Quest headsets were linux/android based, you can run Termux terminal with Fedora/Ubuntu on them and use an Android VNC/X app to run the 2D graphical part. But I share your SteamOS enthousiasm.
