I finally finished Guns Germs and Steel and am heartily glad that I read it. For a book that covers several millennia it's remarkably straight forward and though I can and would pick at some of professor Diamond's detail work (and despite knowing that I don't know anywhere near enough to fully follow this text) I still find this book to be remarkable in that despite covering a huge swath of time, virtually all of human civilization, and very nearly the entirety of the planet I have almost nothing negative to say about it.
