Thanks all for the replies. So what it sounds like (From reading elsewhere as well), that the PDF is getting updates, and the print copies, generally aren't, or at least not getting all of the errata the PDFs are. So as much as I want the print copy, at this point, it would make more sense to save 20+ bucks and just get the PDF. Sad, I really wanted the print copy, but thank you all for the information!
