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
Honestly Valve doing an ARM PC is the first time I’ve been excited about the prospect of moving off x64 (previously it has only been dread and angst for me). If it is open and sets a good standard, I’ll start considering it. With how good Proton has been if FEX is close to that, it’ll be a very smooth transition.
