I received the replacement Voyage 3g late this afternoon. The screen has a much more consistent "cream" tone throughout (vs the diagonal orangish / bluish tones on the 1st Voyage I received).
I'm happy with the replacement. I loved the consistent tone of my PW2 but found my eyes would get tired because the fonts were ever so slightly blurry. The Voyage's crisper fonts are the main reason I wanted to upgrade. (I'm not a physical turn button person -- I'm fine with swiping the screen to turn pages.)
As others have mentioned, I initially thought the origami cover was odd but have found it works great.
I'm happy for those who've received Voyages without any obvious defects, and hope that everyone wanting a Voyage gets a good one!
