We'll see. If revision tracking finally works properly (ie. interchange of Word 97 .doc files with revision tracking doesn't just end up corrupting horribly) then it might be useful. Until then, it's not a usable substitute for Word. I've ended up bringing work home to edit on Windows, because LibreOffice trashed my document.
Of course it would be nice if we didn't use Word format (and obsolete Word format at that), in this way, but that's life in corporateville. Engineering shall toe the party line.
