Valve has been Linux friendly. It says the new steam frame “is a PC” and will run Steam OS but I feel like there’s an insinuation that, like the steam deck, you can install whatever you like. I am cautiously excited at the premise of really digging in and having a Linux box strapped to my face.
Another friend has already referred to it as the Linux Vision Pro.
Edit: watching Linus tech tips review, it mentions side loading Android APKs as well


To further give hope: The Quest 3 is basically a PC strapped to your face. The only thing really limiting you from installing and running whatever you want is the software/OS. It looks like the Frame will be running the same OS as the Deck, so I am super excited as a Quest 3 owner because the Meta Horizon OS sucks and they keep making it even shittier (I can’t do anything I was doing with my headset when I got it now other than running normal shit; no custom software can be sideloaded anymore so all my FOSS programs are vaporized 😮💨).
Wait but I have been side loading on my Quest 3? They disabled the ability to sideload Android APKs? Still works for me.
It hasn’t been able to install from other sources since around 1.76. They removed the default Android package installer.
