LXDE is a new light-weight desktop based on the Openbox WM and PCManFM file manager. LXDE desktop installs the lxde package, which includes these plus Leafpad, GPicview, and XArchiver.
In addition, I've installed:
Kazehakase (Light browser)
Iceweasel (Full browser)
MPlayer (Movie player)
Audacious and plugins (Music player)
Pidgin (IM)
Flash
Java
Codecs
Non-free archives
Let me know about missing fuctionality, but remember that this is a light-weight desktop.
