Windows isn't "grandma" friendly based on the amount of times my grandparents called their children (several were in IT for years) and grandchildren for support over the years after breaking things...

Literally the only devices they could use without incident were Android and iOS.

I'm not a grandma, but wanted a linux that would just work pretty well with minimal effort. Pop!OS (despite the strange name) comes pretty close. I did have some trouble upgrading one version of the OS, but did get it with some help from support (I installed a 'non typical' library). Despite me messing about while trying to upgrade the OS never got into an unusable state which is impressive.

Generally a pretty good experience. I thought initially why bother with another distro, but it seems to be a good experience for me.

The Clevo machines are decent. I appreciate the matt screen and easy open/ replaceable parts (my fan succumbed to dog fur....)

As close as Ubuntu does.
