Honestly for your average home consumer, there isn't much need for a Windows PC now days.

This doesn't mean if someone gave me a manual car I wouldn't try to learn.

If your around a bunch of car people then it's much easier to over estimate how many people will want to drive stick.

Well I can agree with that, but that's not the same thing as being incapable of doing it. Both of my parents could easily install Linux, it's infantilizing to argue that they can't fill out a user wizard and select a drive to wipe.
