Netflix works just fine on Linux, right? Or am I mistaken?
> Or play games.
Most people actually do NOT play the big Windows games you are referring to. They play browser-based games. Work just fine.
> Or have any unsupported peripherals.
Linux' hardware support is actually far superior to that of Windows. Trotting out the 'unsupported hardware'-argument made sense ten years ago. It does not make sense today.
On top of that, it's a bit of a silly point to make. If they don't have a monitor, they can't use it either.
> Or want to use any commercial consumer software.
Your only valid point.
