Postscript: as I have continued using LO Writer for work purposes, I have found it to be buggy enough (no point going into detail; I'll report it to them) that I would stick with 13.1 for the time being because it has OO. I had a complaint from a client because the formatting was messed up. That happened even in the bad old days when I was using Microsoft products, now and then. But I've scarcely had any trouble with Open Office. In a word, I haven't found LO to be as reliable - not just when working with Word files, but in general. I'm sure it will improve in time.
On the plus side, sound works in powerpoint presentations. As anyone who lives in Brazil might agree though, that isn't an unalloyed benefit
