There were a few examples that may not be standards compliant in the book, and in most instances the author does identify these. I did like the fact that the author also referenced Eclipse (open source) and made an attempt at crossing the non-Microsoft divide, although the book is really geared more to a Windows environment.
The book does have an introduction to AJAX and JQuery, but it's not an in depth tutorial. That said, it is a valuable tool to learn what is available and where you may want to identify areas to learn more in another guide.
NOTE: I received an electronic copy of this book for evaluation purposes.
