I went to the site and read some of the stuff. The guy talks about pdf's being cumbersome to work with. I have Real books 1,2, and 3; the New Real Books 1,2, and 3; and 5 other Real books on pdf. It comes with a master list so you can find whatever song you are looking for. I've never had a problem with it. I use it mostly on a gig when someone requests a tune that I don't know. I don't know what product that guy is really selling but I can tell you that I'd rather carry around 11 fake books on my laptop via PDF rather than lugging around the real thing.
