I'm on my second Sony reader, and bought an outboard reading light that I never used even once. I eventually moved it to the Rummikub game box, where we use it to help tell the blue & black pieces apart when we play.

On covers, I am completely addicted to Oberon design covers. They are lovely, very protective, and comfortable to hold with the cover folded to the back for reading. It's worth looking at them even if you're not going to buy--they're beautiful. www.oberondesign.com
