A third author of the book is Dave Johnson. "Dave is the co-founder and CTO of Nitobi Software, a Vancouver-based AJAX component vendor and consulting firm."
I mention this, because I have used Ajax components from Nitobi and they are first class. "Industrial strength" and robust. And as if that was not enough, these components are easy (at least for an experienced developer), to integrate in your application.
I am ordering the book now.

Glad to be here and looking forward to some great discussions I'll do my best to answer any and all questions but my expertise is definitely in Usability, User Experience, Business Case and Patterns. Thanks!
