A few new arguments but lots of confirmation
Lots of confirmation on the kaleidoscope of topics in this area. This is a tough read in "England English" but a strong testament to Dawkins experience, knowledge and intelligence all brought to bear in this Atheist Owners Manual.

Extremely well-thought out and analytical
Richard Dawkins rationally analyzes why there is no god from every possible angle, and why religion hurts societies. Much of the book is like a debate that takes the token responses of theists and then a long and thorough rebuttal from Richard Dawkins. I already knew a lot of the arguments Dawkins goes over just by thinking about it on my own, which many are quite obvious yet need to be stated. The part of the book I found most interesting was how religion hurts societies, which no one really talks about. The arguments Dawkins bring up are very complete and if you're an atheist looking for some added tools in your arsenal of argumentation, this book is perfect for that too. All in all, the book is pretty long, somewhat dry at parts, and is not a quick read either. If you are open-minded and/or interested in the subject I would suggest this book. I don't think the book is going have the intended effect of converting many people to atheism, because believing in god involves preconceived faith not rational thinking imho, but is likely to make more atheists come out of the closet (for lack of a better metaphor) because of the comfort this book will bring to atheists.

Awesome arguments and intense analytical points on the delusional idealism of god and theism
Professor Dawkins compares and contrasts all theories and "proofs" of an existence of a higher being. Using the scientific perspective he voids all arguments pointed out by theists and creationists. Awesome book and I highly recommend it!

Eye opener
After reading The God delusion, a feeling of reasurance and vigor enters one self. Many of my thoughts were properly disected, analyzed and refrased so the path to understand them is clear now.
The book is easy to understand, funny where it would help the point the author is making and the writing is fresh, interesting, fast and it really makes you understand the point Mr. Dawkins is making.
It is so good, so logical and rational, that it will probably exarcerbate the religious fanatics and denounce with the usual hate his thoughts.
Buy this book...

good book
Even if you don't buy in to every argument Dawkins makes (and you probably shouldn't), I think it's an interesting read. Worthwhile.
