It is based on ubuntu and has a clear, simple look. It looks a bit like OS X but also has it's own simple twist to it.
Ok, so far through reading about this, I thought 'I'm going to get this' but then I found Out this:
- It uses avant-window-navigator(maybe you dont, but I hate the way this sucks all my CPU)
- The last update was ubuntu 8.04(slightly old!)
