With all the device support, the EPEL repository, the giant improvements on yum, PackageKit, FreeIPA, new Xorg, and lots of goodness of a desktop distro, if all these made it into RHEL6/CentOS6, I am nothing but very happy and excited.
RH is abandoning the desktop?. So what?. They let the desktop world move on its own, freely, and Fedora _is_ that desktop. What got in Fedora, got into RHEL too. With CentOS set loose on the internet, high quality Free (both philosophy and price) environment is not that far away from reach. ^-^.
