If your interests lie entirely or mostly in the realm of AAA or AA games that are playable with a controller, then I completely agree.

However if your interests lie in indie games or games that require a keyboard and mouse interface (precision shooters, grand strategy games, RTS games, etc) then having a PC that can play games is completely necessary. (I say this as someone who runs linux btw, not a windows defender).

This is key. I work all day on my computer. Why would I want to go home and sit in front of another computer for hours.
