I use Linux since the end of the 1990. Started with Redhat, Mandrake, SUSE, Ubuntu, Gentoo, Sabayon, ... , and now using OpenSUSE Tumbleweed/KDE and Elive.
I already used light desktops like Openbox and E17. I like cool desktops. Enlightenment is very fast, light and customable.
Elive is young and has some rough edges but I see it has a great potential. That's why I've started using it to get to know and understand it and may be help make it better in a near future.
