While I get the „windows bad“ point, linux works for your mother in law a lot better than for you because point and click has always worked well for linux from the reports I read. Please do not steer the tech illiterate to apple. It is dumbed down exactly to attract these figures. If you install a stable distro and dont go with need newest everything that linux elitists spew around, you‘re golden. System76 and Tuxedo Computers are the way to go as far as I can see atm. They even have their consumer ready builds of linux.
