2 Quick Thoughts
1. Eclipse is a reallly sweet IDE. I'm doing a group Java Project for Uni and it's going to be damned useful for that. Even handles CVS :)
2. Gnome 2.5 is looking super sweet. HAIL To the Capt'ns! Cant wait to test all the Gnome network stuff too.
Fast User Switching
There was a whole lot of comments on the fast user switching, and so I've filed a GDM bug. The xscreensaver stuff would be nice too, but IMHO no totally necessary at the onset, and would of course probably require a fork of xscreensaver.
