I am a die hard GNU/Linux user for over 12 years. I have become extremely frustrated in Microsoft products that simply don't work and are a huge pain to maintain, while using Linux and watching it excel over Microsoft products again and again. I wrote my own article comparing Linux to Windows and finally decided it was time to get some more history of GNU/Linux and how it came to be. This book fit the bill. It goes into great detail on Stallman, who created the GNU General Public License and the GNU Operating System which started it all, and why he did so. It does a great job of following Stallman's life and the development of the GPL and other accomplishments of Stallman. It also does a great job of introducing Linus Torvalds and how he contributed the Linux kernel which was the missing piece to the GNU Operating System by Stallman, to form what we use today, GNU/Linux or more commonly called just Linux. A great overall book for learning the history of Linux.
