I was actually quite dissapointed by how the shallowness of the book. It just skims over a dozen of the most important features. I would really have liked some more indepth knowledge, especially on optimizing the performance. As I was already quite familiar with SQL this book unfortunately hardly added anything to my knowledge, which wasn't worth the $35 + $7 S/H. I hope that the newer version will cover these issues a bit more sufficiently.
