I only did it once. Still, point. Joe User? Non Techie? EveryPC? Person who in prior decades had 12:00 blinking on their VCR?
I literally meant grandma, actually. To be honest, mother in law, but it didn't have the same ring. Though grandpa uses the Ubuntu box I set up for him without issue. Their printers are recognized by Ubuntu, be we've had other things that result in tech support calls ( me. ) Every question about some USB dingus, like a camera or wifi dongle, makes me cringe.
I generally recommend everyone buy Apple. Then they can bother their "geniuses" and not me.
