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


The website says 🎉:
That is on the steam machine page, not the steam frame.
The frame page says
Still, very similar… But not quite explicitly stating the OS is replaceable.
I bet it will be. But I’m not sure if there will really be any OSes developed for it.
Some of the early review videos have at least implied that the same applies to the frame, but the frame itself seems to also be ARM based which may limit you a bit.
