Given Apple's history of dumping products I would not want to use Filemaker. The sorts of things one does with a database system one wants to be able to keep doing for the next 20 or 30 years, including having full access to all old data. Apple has a terrible reputation for very poor legacy support. Businesses need legacy support so they can continue to access their data and applications. Unlike consumers we don't want to reinvent the wheel every three to five years.
