Query: Very poorly written

There is some good information to be found in this book. However, the layout is very poor with information scattered across multiple chapters. Considerable time is spent going over the basics of DHTML, CSS, and JavaScript - which is a waste of time for a book of this price. As the majority of the book is focused on BSP development, I was disappointed that the coverage was not nearly as clear as one might find in the O'Reilly series on ASP.NET and J2EE. It's not a complete waste, but most of the material can be found on help.sap.com.
