Definitely not a waste of money., 23 Jan. 2009
I think calling this book a waste of money is harsh. I do agree that the first review is definitely biased and probably written by the publisher, but even though I found the authors a little bit arrogant and pretentious there is a lot of useful content in the book and it's certainly a "must read" if you're new to these concepts...
