I have stayed on Office 2004 for Mac (running on Rosetta, and with the free docx compatibility plugin: I'm pathetic, I know) for the longest time on my laptop just to avoid having to use the ribbon (which I "experience" daily on my Windows machine unfortunately). Since my next Mac laptop won't have Rosetta I'll have to move on, and that means switching to LO, not upgrading Office.

And if LO ends up also using a ribbon, I'll move on to something else.
