Query: Copland Review Very Informative

I know why many of the reviewers gave the book only one or two stars. They were disappointed in that it had nothing to do with the actual product MacOS 8, but instead deals with the vaporware product also known as Copland.As far as it's review of Copland is concerned it is a very interesting book. I wish there was some more detail in regards to some of the low level stuff (such as task scheduling etc.). The book however provided a very interesting view of how Apple was going to try and transition between it's then current OS and a new "modern" OS. The level of detail is high enough to be informative, yet technical enough to provide potential developers with some understanding of how to (re)design their software to work under MacOS 8 Copland.My hats off to the author, even though it turned out to be a waist of paper from a productivity standpoint.
