It doesn't matter. The point is to pass a certain usability threshold above which a device can be used by the average person. PC gaming hasn't achieved that yet but it's getting close.
You have no ideia how average person is... if you worked with support or software development you will probably know better.
Average PC user...
- He didn't read anything and just click ok for everything.
- He can't find a program if the icon is not in the desktop.
- He can't use the Program Menu on Start Menu or the search feature.
- He hit twice every time he uses the left button on mouse.
- He can't find a random button in front page of a program even you saying what is write on the button face.
- He can't back from Full Screen if he entered it by mistake.
- He open the browser icon on Desktop and the home page needs to be Google because he doesn't know how to use the address bar.
- He can't a lot of easy things you will laugh a lot if I list to you but it is that common in PC users.
My mother plays games on PC... she can find the game launcher since it is in the Program Menu of Start.
My father plays game on PC... I have to put the game launcher icon on desktop because it is the only way he can start the game (of course everything is configured by me because if any message happens to shows he can't play anymore).
My father loves to surf the internet... I have to put the browser icon on desktop with the homepage to Google.com.br where he just wrote what he wants and start to click the links Google give to him... if he wants another site and using the back feature didn't back to Goggle he just close and open the browser again.
I give support for 10 years in different companies and there are a lot of PC users worst than my father that plays games like GTA, FIFA, Football Manager, etc for example.
PC will never reach this usability you dream because it is not the goal of the platform and average person will always find it is advanced or hard to deal.
The open freedom of PC where you can have billions of different configurations is an advantage and weakness at the same time... you can have the most unbelievable issues at the point that even a super advanced user having trouble to play games... now imagine an average user lol
