Automatic update of all the software, more support through the Ubuntu Forums (with around 600,000 members and the default chat room generally having about 1500 people), automatic defragging in the background and ram caching, multiple workspaces, operation almost exactly like XP, Vista or Mac (as per user choice), easy installation and special effects like wobbly windows, 3D cubes etc make Ubuntu more friendlier than ever.
