Query: Too basic

Maybe a nice book for people who never heard of the phenomenon Internet.However, for people who want to use it in a real business situation might become somewhat disappointed. There is no strategic implication to be found anywhere in the book and it talks about the subjects in a superficial way. For a more practical book (though it can never be practical enough for me) Dave Chaffey's Internet Marketing book is my best second bet.
