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


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.
