The book is really good, I enjoyed it very much, but the title doesn't reflect what you would expect, at least what I expected; it is not that you learn the Smalltalk syntax or tools, it is more "A mentoring course on clear and creative thinking". (And smalltalk can help you with that!) Just like Beck's Smalltalk best practices book, I believe this book is interesting for a much broader audience than the Smalltalk audience alone. The author's (Andres Valloud) other book about hashing is also very interesting; it's about a (more or less scientific) well thought through approach to analyze alternative algorithms (in this case, hashing algorithms).
