After my review about Arch, I reinstalled from scratch. I started again, building up from the basics. I do this because I appreciate the leanest system possible. Here is a screenshot of my current desktop-
This is Openbox with an XFCE4 Panel. I also use GDM for the login. The total memory usage with Firefox and Pidgin running is 195 MB. This is one lean setup. It boots with Xorg started in about 21 seconds, on an Intel Atom. Arch is my favorite distribution that I have found, and I am sure that it will continue to be so for a while.
