Thanks for the advice... I have to admit I'm torn... if the new model's only real improvement is a light... well, I've got the M-edge book light and it works reasonably well. A built in light is convenient. My wife seems to think I might as well keep the one I have: it has grown on me a bit, and I'm trying to avoid gadgetitis!
I have lots of camera gear, etc. so you'd think I'd be a bit less confused about a single ereader...
