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....)
