Both my parents use linux mint with 0 issues.
my dad is abysmal at tech, never sent an email, hates the concept of passwords etc, etc.
Other than resetting Facebook passwords and replacing a laptop battery, they have never needed a thing from me.
Out of curiosity, what is it that you mom wanted from a pc?
My parents only ever seem to use their web browser, which is identical to the windows experiance.
Why are half of them in prison jumpsuits?
