First of, as a matter of taste and opinion I do not like the interface, but you said it's based of arch which is obviously wrong if you look at the Terminal, where there is an "apt-get" command which is on Debian, (Arch uses pacman). Also on the first line you can see "Rebecca" which is a mint version.
So this basically mint/ubuntu with a custom google theme and some tools.
On a positive note, I like how the linux community is evolving to include a lot of people from different backgrounds and not only developers and Computer Enthusiast. imo the future is in opensource
