I just ran a test on converting a paper from NB to RTF format then to Word (docx) format inside Word. It actually did very well at preserving formatting from the style manual through each conversion process (someone asked me for a Word copy of a NB file I was working on tonight). So for those that need to export to Word, it's a couple steps to get there, but the process is very clean and works well. I'm impressed at how well it actually works.
