Bests & Worsts Reviews from Amazon

I've upgraded from a PW2. The Voyage is smaller and feels denser in my hands. Not exactly light. The display is nice and fonts are smooth, but don't expect a super crisp high contrast display like a modern smartphone with the roughly same ppi (Samsung Galaxy S3 is 306 ppi). The white of the display is slightly speckled. The more troubling issue is the unevenness of the lighting and/or page. The top of the display is noticeably darker and sepia-toned compared to the bottom. I read on the Voyage for a half-hour to see if the effect is noticeable and the answer is: it is very distracting. In effect the brightness changes from dark to light in the span of a single page. Then on the next page I'm back to dark again. See the attached photo. I took this picture in the dark so there is no interference from other light sources. Then I copied a portion of the top and placed it at the bottom for comparison. Update: 27 Oct I did not want to cause a fuss over a problem that would resolve itself, so I held onto the Voyage for a few days of testing. Unfortunately, after 5 days of use, the lighting issue did not improve despite troubleshooting efforts (restarting, auto-brightness cycling, manual brightness adjustments). I contacted Amazon and a replacement is on its way (I was offered 2 day shipping). It is because of Amazon's commitment to its products that I have no hesitation ordering from them. I will update this review after testing out the replacement unit. Update: 6 Nov WARNING: AMAZON SAYS THIS ISSUE IS TO BE EXPECTED. The replacement Voyage had a worse coloration issue than the first. Again, I tried the troubleshooting steps to no avail. I contacted Amazon regarding the issue and came away with the following: 1) Amazon's position is that most people do not complain about this issue 2) The engineering team says that such variations as I have experienced are normal and that all Voyages will have it 3) They will not send a replacement because of (2). I think it's quite disappointing that the company line is that this issue is considered normal. I'm returning both devices and will stay away from the Voyage, from this generation at least.
