Vista on one machine, 10 on another.
Vista was actually good, it just started running slow because the computer was old. Switched to Mint and Lubuntu, those ran faster.
I got a new computer, and went, gasp… BACK TO WINDOWS! Kept planning the switch to Linux for years, because I liked the operating system, then got an SSD and just did it. Installed OpenSUSE, currently on Debian.
Gonna be like the Vietnam War. High tech powerful army vs low tech actually competent guerrillas. Amish gonna win.
