I've been using Mint since Mint 12 Lisa and it is a pleasure compared to anything else I've used. I started on Redhat 4 in the late 80s, at which time I ran a serve for 5 years without so much as needing a reboot.

I have a client with 86 branches which changed to Redhat and then CentOS when Redhat started charging.

They never looked back. No upgrade costs, no application costs, no capital outlay for new features and assistance from willing contributing enthusiasts all over the world, without cost. Its the way things should be.
