On my PC at home I am only using OpenOffice 2 since some months (Win XP) and I'm very pleased
Especially the integrated PDF export comes in handy for me.
I could not judge the quality of advanced spread sheet features, but for every day use at home I don't miss anything.
I was happily surprised to learn that this version also supports some database operations.
So I could access my old record collection DB (MS Access). Well, the DB part of the suite doesn't seem to be that stable yet, but at least I could migrate my records to CatTraxx without the need to have Access installed.
