My experience lines up with this.

Both my elderly parents run Zorin OS on their separate laptops for the past 6 years, they understand as a kind of 'free windows'.

They don't care about the inner workings, they go online, check email, do shopping, make travel arrangements, print a ridiculous amount of paper. And I stopped getting calls because 'the printer is not working'.
