Have a related question, what's the best way to backup N900 contacts so that they can be restored to other Nokias such as N8/N9, and N900 as well? I guess there aren't too many options, it is either PC or OVI suite so really the question is which one?

I owned my N900 close to 2 years now, so far so good and have no plans to replace it with something else, but if it dies I'll likely buy the N9 or have my wife give me her N8 in exchange for something more mainstream, so I want to make sure I don't lose my 200 or so contacts, it will be a major PITA to re-enter them
