I’ve got a new machine running Ubuntu and a very old laptop dual booting XP and Mint. The latter will go only Mint as I sort through all the legacy stuff and move what I need to keep.
With the most recent LibreOffice (version 5), users are able to read/write Office formats much better than with earlier versions of LibreOffice--including tables and other formatting issues that have popped up before.
As far as I know, there is still no substitute for Vizio in terms of reading/writing the file formats.
Everything else, though, seems pretty straightforward--unless you are using some industry-unique, custom software, of course.
