Ubuntu is the entire reason why elderly parents have a functional PC. They didn't need to know all of the negatives vs other distros and just needed the machine they have to work. It has been going strong for 5 years on 13 year old hardware.

I installed KDE for something more familiar and showed them where the internet, e-mail, and solitaire are. If you are the actual typical user and don't need more, then there is no need to hate on any distro at all as long as it will boot and perform maybe 10 functions.
