It will take a few more years for Chromebooks to take over parts of the Windows market share. It's sad but the Steam Deck and Chromebooks are most likely the closest the Linux Desktop will ever come in the next decades.
Installed linuxmint on an old mac mini 2011 and it work quite well. When I think about the tiny desktop format, I believe you can put linux mint on it and got a great general desktop that way, more reliable than a laptop.
