Yet my mom does not have a Ubuntu desktop. And if I set one up for her, I woudl have to split my time between my job and tech support for her. So well funded, but not sure they are the right company.
What kind of issue would you expect that the OS she currently uses does not have?
You're going to have that problem with any kind of change.
My 73yo mom actually runs RHEL 10 on her laptop, uses one of my 16 free developer licenses.
But it would never work without my help. On the other hand, Windows wasn't working too well either and I just couldn't help with that.
RHEL was the most stable alternative I could think of when her Windows computer stopped being reliable.
I have setup rustdesk on it for remote support.
