I didn’t thinking that idea was still in dispute. There have been multiple studies in this area. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3543069/

A steam deck with a mouse and keyboard is kind of horrible, I have tried that. And maybe things have changed, how well does Steam OS do as a primary OS? I might look into it again.

I can sympathize but I hate using the controller setup, I’m definitely a mouse and keyboard person. For better or worse I’m stuck with Windows unless Steam comes out with a desktop or something.
