I haven't gone beyond the basics, as you say, but I use NovaMind quite happily. It is at its best as an elegant brainstorm capture tool. I find that I use it at the beginning of a project (like brainstorming a research paper - I'm a professor) and then export the results to OOPro for refinement. I don't 'go back and forth', so I can't speak to how well it roundtrips.
