As an attorney, this is what kept me from switching to LibreOffice or Google Docs. I gave it a shot, but since the other attorneys I work with (both in and outside the US) and my clients all use Word, I ended up wasting a lot of time fixing files after converting between formats. In the end, it just wasn’t worth it.

I’m fairly tech-savvy, but many of my coworkers struggle with the mental effort required to switch to new software. Two colleagues I greatly respect still use WordPerfect and Word 2003 because they dislike change so much. It's too much of a lift for these people to wholesale switch word processors.
