The Future of the Internet and How to Stop It
Could've been a much shorter book, and it is getting dated in terms of the tech used in the examples, but he brings up some excellent points. I especially like his categorization of generative vs. Tethered appliance. I was already on the path, but this book will push you to at least explore Linux and Android as platforms (even though Zittrain at the time was obviously a Windows user)
