I use it, although I wouldn't say extensively. Whenever a new one comes out, I go to Staples and have them print half a dozen copies and spiral bind them, and then I hand them out to a few co-workers who want a copy as well. (I got the idea of spiral binding them from a vendor who said he hands them out to customers, who in turn seem to love them, but that information is second-hand so don't give it a lot of weight.) I find it easier to hand-write small notes in a Reference Summary than in a Principles Of Operation.
