This one wasn’t specifically a challenge for IT 566 but I upgraded by Ubuntu machine to 11.04, Natty Narwhal. I’m not exactly sure what a natty narwhal looks like, but I’m pretty sure I would want to meet one in a dark alley … errr… ocean.
11.04 replaces Gnome with Unity. The interface is quite a change and is definitely more OS X and Windows 7 like.
