I see this mentioned again and again, but I don't buy it.

For power users or users with niche use cases, sure there might be specialized software that lock you into Windows or Mac.

But for most casual home users, I think Linux would be perfectly adequate, and familiarity being the only real detractor.

Assuming someone can help install a friendly Linux distribution (and that the hardware is compatible), then what are the big blockers? Gaming maybe, for those where it is relevant.

But looking at all my not so tech savvy family members and friends, a browser, online versions of MS Office (or Libreoffice for sure), maybe Spotify or the like, would really be enough. Being able to install apps via an (actually useful) app store is a big win in itself.

Looking at those friends/family members, it is not like they are able to support their Windows machines either when something goes wrong or needs to be changed - I (or someone else technical) always need to help out anyway, fixing driver issues, installing software, changing any non-trivial settings, and so on. And I could just as well do that on Linux - and whether I need to pull up a terminal is irrelevant.
