Although FileMaker & Me was written primarily for beginners to intermediate developers, a number of top level professional developers have already found it to be:
"a great book" - Matt Navarre
"a refreshing take on FileMaker" - Scott Rose
"a unique perspective on building solutions" - Geoff Ryle"
"a necessary resource" - Cris Ippolite
So, if you think that there won't be anything in it for you at your level, you might be surprised.
