This is something as odd as a book written by a political science professor about Open Source, and he manages to create the most lucid and well-analysed piece that exists to date. If you are looking for your standard anti-MS shrills or the religious overtones of a committed technocrat, you are reading the wrong book.

It manages to explain the history of OSS, what it really is, how it works and why we should care. Add to that some legal advise and discussions, and I can't understand why you shouldn't read this book, even if you are no IT-person, as it is very well written.
