OO.org Writer will be adequate as soon as they come out with a decent Outline view. Until then, I and a whole whack of other people are staying on XP rather than Ubuntu primarily because OO.org lacks this one feature!
Personally: every time I use OO, I'm reminded of how much better Word is--in interface (the ribbon is GREAT), features (everything you could ever need), compatibility (you can save in PDF), etc.
Sorry, but it's just the reality. Very few people write Free Software out of pure altruism. They write it because they have a problem they need to solve. Often there is personal gain in sharing this solution with the world (reputation, free bugfixes, etc.), so people do. This is the open source / free software movement in a nutshell.
If this attitude drives you away from getting something for free, then I guess that's too bad. The community only benefits marginally from consumers; it benefits from producers. If you are never willing to produce, the community can probably live without you.
I'm fine with being a producer in a few of the fields I care about (I work on one of the few remaining Perl BBSes), when I'm not busy getting paid to write software. I don't want to have to help write my OS, my Office software, my text editor(s), my web browser, my music player, etc. I just want these things to work in (at least) a predictable fashion.
Anyway, I really do think that the open source community needs to lose the attitude if they ever want to gain traction in the wider non-programmer community.
