Occasionally, I like to try out new linux OS's on virtual box.
At the moment I've kind of converged with a version of Ubuntu downgraded to XFCE with a custom icon set. It looks nice and is super fast too.
But I've just stumbled across http://elementaryos.org/
It looks really nice I'm downloading the iso now and I'm going to try a quick test on virtual box.
Has anyone used it?
