I'm not sure if this is how the Sony case works but I saw a case for the nook at best buy (can't remember the name right now) that was really nice. It was a portfolio type style case and the light was inset on the left side of the case next to the reader right next to were it folds open. The light can then be popped up and would turn on automatically when it was and lit the screen well. The front cover could be held like a book or folded behind. It really is the type of case I am looking for.
On a sidenote I carry it around in the clumsy box for now
