Randomzombie,welcome to MR? It is probably not wise to post your full S/Ns, you may want to mask some of the numbers!!
My PW is 2422, so not a greater number, if they are in chronological order at all. It has a very very very faint color issue, so it's close to perfect. The other two that I got as exchanges and held on to are: one with an overall light pink shade (but almost no green, so somewhat stomachable) and one with very faint blotches and a pin holeon the screen. With ambient light, you almost can't tell, but I read a lot in complete darkness, and there it's more noticeable. I had a total of 9 units in my hands, and I know how you feel about the constant replacements, but the software of the PW is just awesome, so I kept trying for a better screen. I am so glad I did not give up - I love my PW.
