My one complaint, however, is the lack of availability of the example code in the book. Some selected examples can be downloaded from the O'Reilly website but the larger, more involved examples are not available. I have typed a couple code examples from the book and they wouldn't run.

Why bother publishing only some of the code examples? I would hope that, after paying $45 for the book, O'Reilly doesn't expect me to pay another $20 to gain access to the example code on line. This would be enough to keep me from buying another O'Reilly book.

This one beef aside, I would recommend this book.
