> I use LO exclusively and it's a joy to use.

Same here and at several other people who asked me for alternatives over the years. I installed LO (formerly also OO) both on Linux and Windows and they became productive almost immediately. However when I install it on other people PCs I always set the default save formats as Word/Excel/Powerpoint 97-2003 so that nobody will complain when they send files to other people who presumably will be running mostly MS Office.
