I think there is some rule about titles that are questions having an answer of no.

Anyway, I work part time in a charity that refurbishes and distributes old-(ish) computers. Because of the cost of Windows, we install Ubuntu on all of the machines. The only time we have had people report issues with their computer was because we forgot to give them the default password.

I have been using Ubuntu for years, and find that I need to do much less technical maintenance to keep in running than Windows. You install using a simple wizard, reboot, login. You open a program from the menus at the top left (or just left now). The web browsers are identical to there windows equivilent, and the office applications are more simmilar to old-stlye Microsoft office than the new-style Microsoft office.
