I've been lugging this book around for 20 years - finally cracked it. It's preaching to the choir, but it was interesting! I haven't read any other Dawkins, so maybe he does this a lot, but I found all of his reference/analogies to 80s computers really interesting (and got a kick out of some of the more outdated stuff). The narration style really works for me - I like his personal asides and digressions. I particularly liked the section on long-tailed birds. On the other hand, I picked this up 30 years too late - there's a lot of time spent on disproving outdated ideas which wasn't super interesting to me.
