As a fellow Linux guy, it’s just great. I have had to do no hacking and bare-bones minimal tweaking to get things how I want. 90% of games work out of the box, even mouse-heavy games like RimWorld. I just love it. I sit at a desk all day for work. I don’t want to do that after. The steam deck gives me almost my entire steam library and I can lounge wherever I feel like with it. I <3 you Steamdeck.
To add, it’s even reached out to non-nerds. My brother, who isn’t THAT tech literate picked one up and he’s absolutely loving it. He hasn’t had a gaming PC ever but he’s getting tons of time on the Steamdeck and we’ve had zero issues playing games online together and using the steam voice chat.
