elementary OS: Don't Hate Me Because I'm Beautiful

Ubuntu is a very popular base and it's used by too many systems to count. Ubuntu itself is based on Debian, but for now we’ll stick with Ubuntu. elementary was not supposed to be an operating system, and in fact it started its life just as a collection of themes and a few other packages that allowed users to make Ubuntu look different.
