As sad as it is, I tried the RC for 12.2 and if you just click through the installation steps it wouldn't boot. It forgot to create a GRUB2 bootcode partition (EF02 for non EFI boards). I could work around by installing gptfdisk in the LiveCD and create the partitions myself, then use the existing partition table (which requires some tricking to not get the existing layout removed).
Other than that, it has a very huge software repository and better than in Fedora its for all versions! So after upgrade you usually still have e.g. VirtualBox, NetBeans etc. if you enable non-oss or other software which actual is oss but people couldn't find a maintainer.
With Fedora there is always the risk to lose some packages with an upgrade from e.g. 16 to 17 and hope the community comes up with a new version quickly.
If you look for an easy desktop, it actual works to surf to a website with flash, firefox complains about missing plugins and you can click your way through like in Ubuntu.
