Overall disappointing. The authors bore with generally known information that was hip in the early 90ies where it could have been called "visionary". Today this is just one out of thousands of books that regurgitate what kids learn in school these days. In an attempt to make the book more hip, Stan Davis and Christopher Meyer use web sites (how much general does it get than mentioning amazon.com or Peapod.com) to illustrate business models. This might be a good book if you have been asleep for the past 15 years.
