I like the idea of an even light provided by the EL strip -- while it also shines between keys it appears to illuminate the backs of the keys fairly well on a white Eee. But the inverter, batteries, and switch hanging off the back are really kludgy. A mod at http://forum.eeeuser.com/viewtopic.php?id=3735 has an elegant solution for controlling an led hacked into the bezel to light the keyboard. He tapped into the system i2c bus and used an i2c io expander chip (for which there exists a Linux driver) to drive the LED. With a short script to toggle the LED and a hotkey that runs the script, it's a really slick setup. I think the best soution would be to use a piece of sanded plexiglass under the keyboard to act as a diffuser. Light it with LEDs and use the method above to rig a hotkey for it, and it'd be as good as the light on a macbook pro.
