I was looking around to see if there are any other lightweight Ubuntu-based distributions, and I came across wattOS. wattOS R2 is based on Ubuntu 10.04 LTS "Lucid Lynx" and uses LXDE.
From other reviews of this distribution that I have read, the thing that sets it apart is its comprehensive set of power management tools (hence the name).
The other reason I wanted to test this is because I wanted to try to make a "light" version of my Fresh OS respin. Yeah, I know this is based on Ubuntu while the regular version is based on Debian, but I've heard murmurs in the wattOS forums of the next wattOS version being based on Debian anyway. Anyway, this means that I will also be testing the installation procedure as well as a few other things post-installation.
