> Everybody has now moved on to LibreOffice. Is there any Linux distribution who has not switched to LibreOffice?
The Linux distributions do not matter. Even before LibreOffice existed, they were already using go-oo, which was absorbed into LibreOffice as soon as it began its existence. You could even say they were already using LibreOffice before LibreOffice existed.
What matters here is the Windows and MacOS users. They are the ones who are probably still using an outdated OpenOffice.org release, not knowing they could switch to LibreOffice while they wait for AOOo (incubating) to finally do its first release.
