Do normal people who don’t do this stuff for a living use Linux now, outside handheld gaming devices?
I run into folks using linux fairly often in tech hobbies. Ham operators, DIY solar folk, people dorking around with a RasPi, etc. And some Normals who want a lighter experience than Win.
Last dedicated windows box I ran at home was Windows NT 4, IIRC. Last time I had to use it at work was Win7 (?) before I retired. I do have a Win7 virtual somewhere around here I spin up every couple years to run something obscure I can’t get to run in WINE.
