Aura M1 was released way back in 2009! Milestone 2 was froze in December, and testing just completed.
Great news, The Aura GUI is now in Beta!! This means things are looking pretty stable! There have been countless fixes, including the numerous applications that have been added to help make the UI experience more usable.
