"Windows 10 may now be essential". It's not essential. There's basically no reason to use it for normal people. Docs and the vast majority of use cases work in just a web browser. Most office workers should be using a safe sandboxed os like chromeos. You can even do android dev in chromeos now.
It's only needed for gaming, but eventually the testosterone/endless free time for most people runs out and they give up that time waster. And stay off my lawn, kids ;-)
