Re: Divorcing Microsoft
"So for my needs Libre-Office is fine (although I also have Office-2000 with the compatibility pack lying around for reading docx / xlsx). However in my home others need access to Office and the Ribbon because that's what they're comfortable with."
How old is your LO? I've not come across any docx/xslx LO can't read and the later versions also have the optional ribbon interface although it's currently labelled experimental. As I have no familiarity with the MS product I don't know how closely the LO ribbon mimics it but I really found no trouble moving between Office 95 or whatever and OO in the old days.
