One final shot -- here both frontlights are off and I bumped up the contrast setting in KOReader on the Nook to try to get it looking as good and similar as possible to the Voyage.
The nook looks quite good on its own, but the difference between them when comparing is pretty stark and easy to see in person. When I look at my own photos, the comparison seems much closer than when viewing it with my naked eyes here in front of me.
