Re: just to it
"...I've used LibreOffice for years. If my colleagues have a problem with the files I send them, it's their problem, not mine..."
What a frankly shitty attitude.
I bet they love the extra work you cause them just so you can sit in your ivory tower radiating smugness at them.
Back in the real corporate world, you wouldn't get within a mile of any of my teams. We're busy enough without needing another layer of complexity and stupidity making our lives more difficult. Frankly I wouldn't / won't tolerate such diva behaviour. Use whatever product you want, but with that approach it wouldn't be working with or for me.
