I just saw this link on the front page of www.FileMaker.com and checked it out. It's an interesting comparison of RAD software. I remember a little while ago that FM sent out something encouraging people to go to go rank it except Partners like myself weren't allowed to rank it, only end users. Anyway, the report is out and you might find it as something to help sell to people about why use the FileMaker framework and what are comparison's to its competitors. In this survey, FileMaker ranked higher than any of its competitors in the survey.
