So here it is, my Debian 6 Gnome 2.x desktop.
This is a list of my current customizations.
GTK Theme: BSM Simple - http://gnome-look.org/content/show.php/BSM+Simple?content=121685
Icon Theme: Dropline Neu - http://gnome-look.org/content/show.php/Dropline+Neu!?content=38835
X11 Mouse Theme: ComixCursors (Opaque) - http://gnome-look.org/content/show.php/ComixCursors?content=32627
Desktop Wallpaper: Carbon Gnome Wide - http://gnome-look.org/content/show.php/Carbon+Gnome+Wide?content=140430
Has Debian 6 ended my distro-hopping madness?
I have been looking for a solid, reliable and usable distribution for quite a while now and I believe Debian 6 is the answer.
Debian does exactly what I want without any fuss.
Although for a better experience I am using a customized 2.6.39 Kernel, Iceweasel 4 and LibreOffice 3.3.2.
Nonetheless, its long release cycle, good support and documentation from the Debian community, and overall no nonsense characteristic have made a firm impression.
The long release cycle being a major factor, I think by the time Debian 6 goes EOL Gnome 3 will be in a much better state.
