I mean, the nuance you describe is notable. But I sit on the couch, using controllers and play the same games you would on ps or Xbox. Both of which run variants of Linux/windows.
K… This is just not true. Plenty of AAA games run well on the steam deck. Currently installed on mine, RDR2, cyberpunk 2077, horizon zero dawn, Forza horizon, uncharted legacy of thieves, the last of us, and for funsies I just started another fallout 4 playthrough. I’m sure others have lots of other AAA games they play on their deck.
If it’s the exclusives you’re missing, like Gran Turismo or something, I think that’s a different argument.
