Some form of lighting, like the front lighting in the nook would be nice. As far as the battery issue....don't use the light. I'd rather have it and be able to use it when needed. When I used the nook glow I thought the light was very nice and useful. Regular lights result in glare off the screen. It does appear that the new kindles will have lighting:

I have no interest in Kindles as they don't support epub and am not interested in converting files.
I did read about that scratching issue on the nook..so that put me off from buying one plus the sonys are just packed with far more features...and look cooler
If I could find a prs-t1 for $39 clearance price I'd just get it and not bother with whatever is coming out.
