I always have been a alpha to beta junkie. I like to test new system (in this case Ubuntu). Right now I have upgrade my Ubuntu 10.10 to Ubuntu 11.04. This is the beta version before it reached stable version. The most notable changes from Maverick is the Unity Desktop. I would not go into detail on the difference between Maverick 10.10 and Natty 11.04, but if you are interested to know more, I will post it later.
