Bests & Worsts Reviews from Amazon

Let me first start off that I am a loyal Kindle user (and will continue to be) who has had 1, 2, 3, 4 and the touch, and now the Paperwhite (PW). I have been consistently, without fail, impressed immensely with each iteration of the kindle and say to myself year after year "they did it again." I buy the day each one is released. Customer service is top notch and has always been. I received my first PW last week and it had a LOT of discoloration in the dark (as if there were three colors on the screen - pinkish, bluish, yellowish). This wasn't just the four leds at the bottom which caused some shadows at the bottom (which is not a problem for me) but splotching on the screen's middle, upper left and lower right. I did some research on the online boards and found that there were a good amount of people who had the same concerns so that made me feel reassured that my eyes aren't defective (20/20 no glasses, btw). I returned it no problem and got my second PW unit today and it's an improvement. The tone and contract is more yellow/brown and closer to the raw e-ink display i've come to love but I still see shadows (people have called them clouds, shading, a marquee effect, tints) that makes me want to chuck the PW aside and grab my k4 and flip on a lamp. During the day and in strong lighting, its fine. but in the dark, both of my PW's are below the kindle standard i've come to love. I will concede that compared to the nook glow, the new PW blows it out of the water but the standard Bezos has set is high and i think with some work they can/should keep it. It seems more of a hardware issue than a software issue. The fine tuned fonts are nice on the PW but they're lighter than on the K4/Ktouch (this is something i think they can work out in the software). It is true with front lit lighting, its nearly impossible to have uniformity but splotching and "clouds"? No bueno. All in all, I really want to love the new Paperwhite but its coming out of the gate as extremely flawed. Concept is a 10 but in practice its coming out as a unit i'll most likely return if my eyes can't adjust after a few days. I've read on boards of people trading three or four times and still unhappy. This is of course a minority but i'm confident Amazon has a team on it now and is getting to the bottom of this. Given the subjectivity of light perspective, it should be noted that at least five people on the boards have said their second one is more yellow/brownish which gives credit toward there being uniformity on opinion on some issues in regard to the new PW's. Sidenote: (Going from 150ppi on the k2 to 167ppi on the k3 was awe-striking to me and i thought for sure the 212ppi from the PW would floor me. Unfortunately, it hasn't. Part of it being because you can't compare it truly when the new PW light does not turn off fully even when at #0 on the light adjuster (this makes no sense at all, btw. why not give the user true power and afford them the opp to turn it all off if they like). And given, with two added layers (the light layer and the touch layer) can't not affect the screen, there is clearly an issue with discoloration shadows of pink,blue, and yellow according to different people's eyes. PLEASE update the software to allow users to turn off the light if they want to!!!
