Life Beyond Windows

If you had to switch to a Windows alternative right now?

What would you switch to or install? Either Linux Distros or other systems?

Me:

Ubuntu on my main machine, using Microsoft apps online.

Laptop

ThinkPad T470, with either Debian, Ubuntu or Elementary OS. Still utilizing online Microsoft apps

Chromebook for casual use and secure banking.

Gaming

My main machine along with a PlayStation

I feel I could live without Windows just fine. It is really not the only operating system in existence. It is certainly not 1998 anymore, with all the choices.
