Thanks for the kind words about the book...
I'll add some more kind words. I got the Evening book for my wife (which I read before giving it to her) and the Ultimate Workshop book for me (and her after she is really ready for it). I found both books very valuable, but the Workshop is really great not only for the technical points, but for your thinking as you approach a problem.
I am a member of a large photo club and occasionally do presentations on Photoshop for them. When people ask for good books on CS5 I enthusiastically recommend both of these books!
