I took the plunge (I had to get it online sight-unseen, don't get the opportunity to browse) and got the 2006 reader last year, and I've gotten plenty of mileage out of it - I pick it up and read a bit every now and then. Some really interesting articles. So its nice to know the 2007 will be just as good. I might even pick up the 2005 if I see someone selling a copy. I almost wish they'd leave out the calendar part, not really enough substance in it for me, and being in a bound paperback, not very functional. But well worth it for the rest of the book.
I even like reading the reviews - interesting to see how others think about particular decks, even if I don't want the deck - you know, how they approach it....
cheers
