Query: Idle Boasts

Contrary to the claims made on the back cover, Williams' beginner text offers nothing that could be considered "the latest in PCB tips, tricks, and techniques," and its "expert comparison of CAD program options" are largely regurgitated verbatim from the EAGLE help file.In the software world, programmers who buy books to expand their skills expect insights not apparent from the software vendors' help files. Hardware folks, even beginners, should expect the same.The only user who I imagine could find value in this book is an absolute, complete rookie who's never used EAGLE before and who prefers a guided walkthrough to spending an equal amount of time simply reading and experimenting with the examples in EAGLE's generally good help system.
