I don't think OOo is for everyone. If you know Word already, and you're doing the things that Word does well... might as well stick with it.
But take a large (300 page) document with tables and images, create a Word version and an OOo version, and have a race to open, edit, update fields and PDF it (with hotlinks etc included). The Word person will generally be weeping after 5 minutes

That's why I use OOo in preference to Word. Although I'm not fond of MS, either.
