You cannot compare this book to the Web Application Construction Kit series as it targets a completely different market. I purchased this book to get a crash course on some of the new AJAX features built into ColdFusion 8. I found it easy to follow and very well thought out. It's a one stop book covering all the basics and some of the more advanced and powerful features in ColdFusion 8.
If you are learning ColdFusion or new to some of the CF8 features I would recommend this book over the Application Construction Kit series simply because it has everything a beginner would need to get started, but even if you're an advanced CF user don't discount this book as it serves as good refresher.
The only negative for me was the very brief mention about Eclipse in `Tools'.
To me this book is printed tutorial as it states on front cover; the writer claims that the book would be beneficial to beginners as well as advanced developers; unfortunately this is not true; as the book does neither targets beginners truly nor advanced programmers; many times the writer drags readers with assumptions of knowing the bits and bytes of the topic; the best way to learn ColdFusion is:
First: Read "Programming ColdFusion MX: Creating Dynamic Web Applications / ISBN-0596003803" to start although it's outdated a bit but it's not bad as start point.
Second: Carry on and upgrade your information and knowledge of the new features in CF8 using ColdFusion 8 Developer Tutorial we are reviewing. ---------------------------- Pros. of the book: -Well organised and written. -Referencing all possible related IDEs and software. -Covers fairly advanced topics and API such as Google Maps.
