Elementary is based on Ubuntu, the current version is based on Ubuntu 12.04 (ie the last long term stable release)
It is new and not very mature, but it is perfectly usable, and VERY nicely designed - not just looks, but the UI is excellent.
It does have a MacOS like dock, and is less configurable than most Linux desktop,s but thanks to the excellent design I am not inclined to mess around with it anyway.
The only thing I can find really wrong with it is that it does use vertical space very well compared to Unity - otherwise I would install it on my wife's netbook as well as the visitors/spare desktop. Its not for everyone, but its very simple and well designed.
