With all the interest in the OS and office productivity suite package, someone had to come up with a book to take IT enthusiasts along for the ride. O'Reilly Media's Exploring the JDS Linux Desktop, by Tom Adelstein and Sam Hiser, is an ideal introduction for the novice to more advanced user, especially since it is packaged with a live CD-ROM that lets you run the OS from RAM without installing it on your computer.
The book is clearly designed for getting people up and running on JDS fast, so while it will be of great interest to hobbyists and employees who have been switched over, it's not designed to make the reader a systems engineer or serious administrator. It's also one of the few JDS books that I've found on Amazon.com.
JDS is specifically designed to be an "easy" version of Linux to use.
