I must admit to never having been a fan of CentOS, funny really as I started out really liking, and spending a lot of time with the early RedHat (1.0 - 4.1) releases.
I must admit that with every new CentOS release, I download it and install it in a VM and play with it for a few days before going back to OpenSuse.
I'll probably give the rest of the 5.x a miss and wait for a RH6 based release due?
