This is my screenshot with Ubuntu 8.10. I can say I'm very glad with ubuntu's performance.
As you can see... the background I took it from fedoraforum.org a while ago (no longer available since fedoraforum.org banned its galleries). It is originally Width: 2560 pixels x Height: 1024 pixels for a dual monitor), and the icon set is Meliae-Dark from Sora's factory (it can be found in here). I'm using Avant Window Navigator, Compiz-fusion, and Emerald Window decorator.
