My favorite is Ubuntu.  I run Kubuntu on my desktop and only Ubuntu on 
my VMs.

I am a fan of how easy it was to configure a virtual host on CentOS.

Did not know that.

Thanks for the heads-up.

I'm all in with Ubuntu.

Started my Linux journey with RedHat. Shortly thereafter I converted to 
Debian.  I was a member of the Tucson Free Unix Group and they were all 
in for Debian.

I used CentOS because I had a client that was using it.  As I recall 
CentOS 5 was out for a long time.  Then there was 6 and then it died.  
Am I correct?
