I've seen it and it seems pretty good. Unfortunately, not available for a Mac.
I use FD (after many years of using Scriptware) mostly because of it's ability to export in a wide variety of other formats. I like to export as a rtf, open it in Word, do a grammar check and then put it back into FD.
I also like FD's report structure for analyzing page counts, character stats, etc...
As for industry standard, I think that pdf's are the industry's choice for accepting (other than a hard copy). However, once you get into collaboration with other producer's, the ones I've dealt with use Word and prefer a doc. But that's me...
