The other books spend more time easing the reader into concepts like immutability, pattern matching, supervision hierarchies, and the concurrency model. This book is for when you're sold on Erlang-the-language's overall design, but still not sure about how to set up a real project on Erlang-the-platform. I'd recommend getting all three, or one of the other two and this one. I like the Armstrong book's personality more - Cesarini's seems better organized, but a bit too serious. Also: ErlangCamp was indeed fully awesome.
