Re: The Linux Struggle
I've been a Linux enthusiast for getting on for 20 years and spend most of my computing time using it, but I have a Windows VM as well. The reason? I was doing proof-reading for international students and I had to be able to guarantee compatibility if I was going to feel OK about asking for payment. Open/LibreOffice is fine for simpler documents, but not for some of the things these people were doing, and the last thing you need is to find something missing when you're half an hour from submission deadline.
Use what works for you, and don't worry about the "shoulds". There are no bonus points for being Windows-free (or Mac-free or whatever else it is you need to use).
BACKUPS are unsexy — until you discover you should have done one yesterday.
Spare your nerves and do one before you upgrade or install.
