Linux distributions tend to fall into one of two camps. The first are those, like Ubuntu and Fedora, that are aimed mostly at enthusiasts and others happy to teeter on the bleeding edge of technology. The other group consists of more stable, commercially supported software, designed for those after less excitement, and includes products such as SUSE Linux Enterprise and Red Hat Enterprise Linux (RHEL). New releases are a rarity in this category, so when a major new product like RHEL 6 comes along it's a big event, and one worthy of close attention.
