I considered it because it does look like an excellent product, but I can't justify the cost as I'm not a coach. If I was coaching for a living I would have bought it in a heart beat.
A friend of mine who is a personal trainer bought it. He is a big fan of Robertson and Cressey and has been doing the online training thing with Robertson. If I recall correctly, his impression was that it was great to have all together as a reference but a lot of it was already available for free on T-Nation over the course of a number of articles. This guy has already bought Inside Out and Magnificent Mobility. If you have those plus read the articles on T-Nation, the price is not really justified. If you don't have their other stuff, there is a massive wealth of information on training smart and safe and as a standalone product it probably is worth the price, especially for a trainer.
