Please consider a different/lighter default desktop background. A beautfiul background (shared by Gnome/KDE) goes a long way in improving first impressions of a system. A good example is the Suse default background. It gives the impression of lightness and looks highly professional. As a result, even new Linux users are impressed. This is a small thing of course, but I believe it is important for first impressions. People who view the default startup screen are immediately 'wowed' and it would be nice for their first view of the desktop to be the same.
There's a big dragonfly in there now. ;-) don't worry, just for the beta.
Closing, we have the final desktop background lined up (but rawhide still has a placeholder).
