Heh, I fired up Libre Office a while back. Built up a home machine that does run Windows 10 (some embedded dev tools I want to run with low hassle), but all software on it is either OSS, or free beer type software.

No 365, lol and the Win 10 pro license was $5 (electronicsfirst.com)

Libre Office is GREAT. I have not used it in a while. In a couple hours, I had my styles, fonts and goodies all setup.

Making docs and a fairly detailed presentation were a pleasure.

Office is degrading rapidly right now!
