Topic: Ubuntu 11.04 (Natty Narwhal) Makes a First Appearance

[sam]

The Alpha 1 Release of Ubuntu 11.04, often known as "Natty Narwhal," is intended as a "developer snapshot" of the next major Ubuntu version, which is due in April.
That version has already generated considerable interest and controversy in recent weeks, most notably because of Canonical's announced decision to use the 3D-enabled Unity interface in the desktop version of the application as well as the Wayland graphics method.
