Interesting book - well written and interesting, provocative ideas and anecdotes. I think, however - especially after conducting a pilot research project and reading many other studies - that Tapscott (and others, such as Marc Prensky) oversimplify the situation. Yes, many members of the Net Gen have grown up with technology and use it for many things in their day to day life, but so do many 'older' people - many who actually invented the technology that Net Geners use. Study after study show that Net Gener's use of technology is often superficial - ie, just because they use technology often, does not mean they use it well. In short, for many people, what Tapscott says is true - but for many others, it is not.
I would definitely recommend this book - but read it with a critical mind, don't accept everything at face value. It provides much food for thought. Like some others, I would recommend this book to educators (which I am) - technology does have the potential to engage students, open up new possibilities and to transform education.
