In my experience, windows is an awful UX for gaming but it is very easy to install and run unauthorized games. Steam deck requires a bit more heavy lifting and patience.
I ran windows on my deck for a year and switched back because the experience is terrible and nothing works quite right. I haven’t used the newer windows handhelds, but the upcoming ROG might fix some of the issues with booting into windows and doing constant updates
Linux/SteamDeck = Good Anything else = bad
Porn games should be available for all, but GOG sucks because they did something shitty years ago.
The only thing worse than a right winger is the wrong kind of leftist. (I feel this is a global thing not only US)
