Windows is still the king for gaming. Word is better than Google Docs for anything but the absolute basics[0].

[0]: Please tell me how I add a new paragraph style in Docs?

I don't think you can add a new paragraph style in Docs. However, 99% of people I've known to use a word processor have never used that feature. Heck, I'd bet the majority of users don't even understand what a 'style' is; people just change the font size directly.
