It’s for people who aren’t tech literate.

My experience installing Linux for tech illiterate parents and grandparents was lovely.

They never noticed they're not on Windows. They just wanted their two desktop icons - web and email.

Edit: Funny related story - they (grandparents) always rebooted with the power button after Linux told them it had updated - which was almost never necessary. I always just told them "good job", when they mentioned it, though.
