ah, yeah.
When I need lightweight I use xfce, its got a little mouse for a logo, and I like those.
Enlightenment is about as lightweight as xfce but far prettier and imho more conducive to workflow (YMMV).
im mostly anti KDE. Never cared for it.
I've played with both and wasn't really impressed with either. I mean I can use either of them just fine and they both have good and bad about them, but for me there simply wasn't anything there that really stood out.
Right now I'm using Elive on the eeepc. It works superbly. I'll be putting it on the F5 soon for use as my primary OS.
