I've pretty much acted like 7 is EOL for the past year or so - there isn't really going to be anything dramatic once its "officially EOL" there are way too many businesses, etc. still using it for them to drop all security patches, etc.
Two aspects to that you are missing - down the line not installing it is a less than desirable option - it isn't like there are many options in the long run for DX12 gaming, etc. and the Windows eco system in general will gravitate towards it - it isn't like other products i.e. where you have a broad choice of cars that all do roughly the same thing and the second thing is that there are many aspects of 10 that are good (or should be) and despite the impression some get I'm not interested on sticking on Windows 7 forever while it does many things well there are many areas where it is dated - I don't know why so many people are happy to settle for second rate with Windows 10 when it could be so much more as an OS.
I don't need an OS to be perfect - 10 falls short on many fundamental aspects that should be nailed down out the gate - this is pretty much indisputable - there are so many tech articles and even users posting here who otherwise like the OS that pick aspects apart like onedrive functionality that really should be robust and well implemented from word go let alone still wanting over a year on. It isn't easy to "let things go" when they are central to your usage experience.
