Linux only here.
For pushing a decade.
Four boxes at two locations. [redundancy is not just a good idea....]
I have too much time and money invested in Windows software, along with games that will not run in Linux. But I do dual boot all of my laptops except for one with Ubuntu Studio and Windows 10 Pro.
I also have a Ubuntu installation on a USB stick that will work with almost any computer that can boot from USB. It is a “persistent” installation meaning that whatever changes I make or work I save are ready to go in whatever host machine that I put it in.
For pushing a decade.
I've been Linux-only for over 20 years now.
