Before I bought a Steam Deck I had never used Linux but now I really like it, honestly I'm tempted to install SteamOS on my PC as it's only ever used for gaming anyway
Same, before steam deck I remembered my literal 15 year old terrible ubuntu experience.
Nowardays I can say for from my experience as an ex MF mentioned in OP, is that those MFs think is a linux experience, is just projecting current state of windows.
Idunno i just click "update" on whatever the appstore is called on this window manager and watch it go brr.
Terminal is mostly used for ssh and tunnel for some schoolwork or starting a database server. Which you have to do after installing extra programs on windows anyway.
