I've always found the Enlightenment desktop fascinating. Maybe it has something to do with all the shiny. It's a great balance of eye-candy and performance, and with a little tweaking, can be turned into an awesome desktop system. That's what ELive is. It's a live CD (installable) based on Debian 4.0 and using the Enlightenment desktop- both E16 and E17.
The boot process went smoothly (despite being interrupted occasionally by some dialog boxes), and the install icon was easy to find. The fact that it was animated helped a fair amount. Hardware detection was incredible; my native 1280x800 screen resolution and dual-core processor were detected out of the box, and my Intel PRO/Wireless card only needed a package to be installed.
The desktop theme was also great. Since I'd already tasted E17's default "Bling" theme (the one with all the shiny), I went for a faster E16 desktop and tried the new "Night" theme, which was too subdued for me.
