I can remember some years ago, when centos was lagging 5-6 months (or 
more, can't remember exactly) behind RH to release version 6, and the 
developers answering to the question "when is it going to be released?" 
the unprofessional "when it is ready". This is how I switched to SL 
which has always released more or less in time. I like the SL logo too !
