Query: Excellent COM book, first chapter in particular.

This book is well worth the purchase price for the first chapter alone. The first chapter gives the best description I have ever seen of what COM is designed to do & why it is implimented the way it is. This desciption is done in an amazingly clear, well-thought-out manner. The rest of the book is quite good, but the first chapter is genius. Buy this book
