With less than two weeks left for the final release of Ubuntu 12.04 LTS, this video shows the performance of Ubuntu 12.04 after 16th April updates. The latest updates stabilizes the OS even more and adds Unity 5.10, which brings a nice little animation during installation (although, for me, the animation is a bit too fast!) of apps from Ubuntu Software Centre.
The video also highlights the performance lag with the latest NVIDIA Linux driver, 295.40.
Ubuntu 12.04 is slated to be released on 26th April, 2012.
