Gnome 2.8
I upgraded my Gentoo machine at work from Gnome 2.6 to Gnome 2.8. It runs much better. I’m really impressed with the work the Gnome people have accomplished. Performance is noticeably better. And the file dialogs don’t suck. I’m upgraded to Evolution 2 as well. Primarily because the attach dialog was crap in 1.4. Too bad the Exchange connector was/is broken and required some patching. Ugh.
Highly recommended. Applause all around. Now if I didn’t have a total crap video card at work.
