I’m running a virtualized linux on top of a linux server. I have only one windows 7 virtual machine and some old windows laptops and tablets that I no longer use.
I use a raspberry pi ‘head’ to virtual machines right now.
And for those who don’t believe in linux desktops, I’ve been running linux since its experimental days in 1995. Back when there was only one distro to download and two other even-more experimental ones. In the rare cases when I can, I ran x-windows with a mouse with three buttons.
