A couple of stories spotted this week on other sites:
It seems Bibles suffer similar problems to Filofax Organisers... they won't lie flat when new. Also useful tips on which Bible is similar in size to a Filofax Organiser.
An earlier article on this same site has some excellent pictures of other organisers too.
Another use for a Filofax in the home for collating recipes. Which got me thinking about a design of a suitable recipe template may be? Sketch out what you think it would look like and email me a scan.
