The back cover states:

Dear Reader,

Since its initial release in early 2006, the PC-BSD operating system has quickly become a popular desktop for both novice and experienced computer users. Novice users are initially amazed that such an attractive looking operating system is available for free. They quickly learn that it is also easy to use, free from viruses and spyware, provides the applications they need to perform their computing tasks, and has a large selection of additional software to choose from. Advanced users appreciate that it is built on top of FreeBSD, an operating system known for its security and stability, yet it still allows them to explore and tweak the system to meet their needs.

This book is written to the latest release of PC-BSD. PC-BSD version 8 provides many features, some of which are not available on other operating systems. You will enjoy learning about these features and trying them out for yourself.

This is a book you can grow into. The beginning chapters quickly get you familiarized with, using, and customizing PC-BSD. As the book progresses, you are given opportunities to dive deeper into how things work. If you already consider yourself an advanced user, you will still find yourself saying "I didn't know I could do that" and will find many activities to further increase your knowledge. This is also a handy reference book for when you need to answer "how do I do xyz?" We recommend that you have several copies hand onone for yourself and another to give to those friends and family members who are always asking you to help them with their computer!
