>> Excel is, in and of itself, a single reason alone for many people in various industries to own or operate a computer.

I had a client that suffered an excel/windows ransomware attack. It started with a macro or something in an excel document that, for some reason, everybody seemed to open. My inbox was flooded with "do no open anything" emails. Then the CEO called me to check on the data I had stored on my systems. "Remember when I said I didn't use windows? Your data, at least the copy I have, is safe."
