I am the average user. Linux is, and has been since at least 2012 when I started using it, been absurdly easy to install. You can get instructions for it in seconds, follow the directions, and you’re done in twenty-odd minutes. And I mean done as in you can do any of the basics the average user needs to do. If you wanna tweak things, that’s longer, but still as easy as windows (or easier in some aspects).
My fucking mom can handle a mint install, and she’s an idiot in regards to computers.
