I am feeling rather comfortable with Linux now. This is my current Ubuntu 9.10 desktop:
Windows (Firefox and Amarok)
Plenty of tinkering however I am extremely happy with the results. I have even manged to theme the Gnome Indicator-Applet-Session daemon which is something most icon themes miss. Next bit of tinkering involves the KDE icon theme so the KDE apps (like Amarok) icons are more consistent with with my Gnome theme. Likely I will combine a black version of KDE's Oxygen theme (particularly folders) with my Gnome icon theme (Magog White).
The GTK+ 2 Theme is Fundamental combined with the Lithium Metacity theme. Wall paper is from Interfacelift.com.
