At least what Apple/Filemaker should do is have a free FMP database viewer/editor application (without development abilities) that runs on Macs/PCs much like Filemaker Go on iOS. It's pretty ridiculous to be forced to pay $299 to have the dev. version installed on a workstation that will be only used to do some minimal viewing and editing.
Maybe you should wait and see what FileMaker 13 has to offer. My full-time job is FileMaker dev work, and it does amazing things.
