Query: A good IT book

I suppose it was pretty easy for Bill Gates to write a book on the information highway since he contributed so much time on the road construction. It was good that he reviewed the events in IT prior to the web explosion. I liked the CD enclosed with the book (it was a good marketing strategy) and really made the book come to life. I'm anxious to see what he will come up with next.
