heck it's still Linux and pretty much the same.
There's a lot more than just a kernel to break a system.
Red Hat went far too long between releases and it is clear to me that I can't possibly rely on CentOS for timeliness.
Maybe I'm just in a different kind of environment, but why do you *need* more frequent releases? I still run some servers on EL 4 and will only migrate them when they approach End-of-Life status. They work and are up unless I bring them down. Security patches are still being pushed out for them. Sounds like you're looking for a desktop linux - probably best to use Fedora/Ubuntu?
