Query: Authors do not know the computer industry

The authors are PH.D. economists, but obviously do not know how the computer industry works. I've been in the industry over 40 years and had to deal with the IBM and Microsoft monopolies. Much of the text deals with dead issues like Beta vs. VCR and QWERTY vs. Dvorak keyboards. If you are interested in these topics, the material is complete.The rest of the book is a defense of Microsoft and tells us that Microsoft is a success because of the quality of their software. They do not mention the hundreds of bug fixes and security patches Microsoft sends out regularly. Most people in the computer business will laugh at some of the statements in this book.
