With the release of Ubuntu 10.04, feature tours, installation and other videos have started springing up. You can read about them all you want but nothing works like a visual.
The 10.04 Lucid Lynx has some nifty new features and this video will tell us about most of those features in details.
Although this release is in high speculation it is not as perfectly designed as the version 9.1 was. This is because of some core changes which will need time for a better overall integration with the overall environment. Lets hope for the best with the next release.
