Is Online Office 365 good enough for you? Or, is an ‘almost fully compatible’ word processor enough?
The features are there, but it’s a whole new interface to learn, and if you export to a word document, the document produced may look wonky when viewed in word. OTOH, whatever PDFs you produce, those will look right. And if Online Office 365 is enough, that’s great, because you won’t have to worry about that.
You’ll need to establish a workflow, and others in your office will need to use (and get used to) the same workflow.
It’s not a small leap for an office to take. I love Linux, but check out that it has what you need before you fully commit. Give it a try by dual-booting or by installing it on a secondary system.
