Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

While the attempt at unifying the desktop is admirable, it is lackluster. This week I have had the opportunity of attending the RH 253 Networking and Security Class. The class is good, not great. While I have learned some new skills, I have to say that forums like this one have been a better source for education.
The operating system has stripped down versions of popular programs such as nmap (need for discovering services and network topography) and the new top is not very accurate. We were unable to change the clock via the gui so they still have some minor things to work on.
As an aside, don't count on Redhat to be the leader in support for viewing DVDs, they won't even issue a laptop that contains one, much to my teacher's disapproval (a few moments rant about Open Source...bleeding edge....blah, blah blah). The presentation about setting up DNS and sendmail were great, and the labs were challenging. The computers are 600 MHz PIII from Gateway, and they are so damn LOUD. Sounds like a jet taking off when the HD start cranking.
Redhat has taken a leap, with the new release one that I am not willing to make with them. I will stay with my customized current version of 7.3 w/ KDE.
Thanks to everyone who contributes to the wealth of knowledge on this site.
