There's a market for everything. You don't understand my use case. My use case is "I want to click a button and then I want to be able to `apt-get install what-i-want` and then it should work. I don't even care whether it's Debian or Ubuntu, as long as it has apt-get because that's all I understand.
Granted, maybe I shouldn't be running VPSes at all but hey, it works, and I bet DO has many customers like me.
