I wanted a book to give me the knowledge for installing ESX 3.x servers. Chapter 1 is ok for installing v3.02 but not v3.5 (the current version). The book is filled with typos and grammatical mistakes. Chapter 2, "Installing Virtual Center" is the same directions repeated for each screen with no explanation. The book suffers from a lack of option explanations, and is therefore useful only for a test setup of VMWare.
