Sticking to its 6-month cycle, the Ubuntu team has today let loose its Natty Narwhal aka Ubuntu 11.04, the latest version of the (reasonably) popular open source Linux distribution. This release comes has the Unity interface replacing GNOME, as well as other goodies.
Among those goodies are the new, configurable launcher (found on the left-hand side of the screen), the fresh dash which brings together everything from documents and applications to music and video files, a workspace manager, full touchscreen support, an enhanced Software Center (now enables users to rate and review apps), an upgraded Ubuntu One cloud service, and, of course, updated software packages.
Ubuntu 11.04 (in Desktop and Server flavors) can be downloaded via this page .
