I never read 'The God Delusion', but I saw Dawkins give a talk on the same topic, and I loved it. However, many of my peers thought it was overly obvious, simplistic, etc..
But I have to say, he's a very clever man.. His wit and general knack for beautiful analogies shines through even when he's straying from his field of expertise (evolutionary genetics).
My two favorite points from the talk which stuck with me quite vividly (it was over a year ago I'd guess)..
1) He challenges the Intelligient Design arguments that try to reduce natural selection to 'random' processes by comparing it to the art of cracking a safe. Of course the amount of time it would take to open the safe is inordinately long if you're just trying numbers at random, but if you have some subtle guides, if you can listen for the little ratchets and clinks that tell you when you're getting close, then you can drastically speed up the process.
2) Regarding the inculcation of our youth:
He shows a picture from a newspaper article, showing an ethnically/religiously diverse group of children sitting together in costume for some sort of christmas play. It's captioned something like, 'Bobby the Protestant, Joseph the Jew, and Lisa the Sikh, all aged four'.
Naturally, the first response is to say 'Well isn't that nice, all those kids are friends and getting along despite their diverse backgrounds.'
But then he points out the ridiculousness of assigning such potent and all-encompassing world views to young children by going through several rounds of substituting different sorts of (non-religious) philosophies into the caption. (i.e. 'Bobby the transcendentalist, Joe the libertarian and Lisa the epiphenomenalist')
I agree that he's much less fun now that he's an constant anti-something, but he still presented a good (and far less biased than I expected) set of arguments.
