While I chose to focus on RPM and Red Hat for this article, it shouldn’t been taken that this book will focus just on Red Hat’s Linux distributions or just on RPM.
One important thing to remember: one of the advantages of Linux is that There's More Than One Way To Do It. (Yes, that's Perl's motto, but it works for Linux as well.)
You have general-purpose distros like Red Hat, SuSE and Mandrake, but you'll can always find a distro that best fits to your needs.
Do you want an easy distribution? Try Lindows. It may be as insecure as Windows, because you can do everything as root - but it's really easy to use.
If you want the greatest security, check EnGarde, Trustix, or even NSA's SE Linux.
Don't have a CD-ROM? Tomsrtbt to the rescue! ("The most GNU/Linux on 1 floppy disk.")
And, of course, if you want to avoid the RPM-hell, use Debian!
