Not sure why are you so worked up. I got impression from that the yellowing and uneven back lit are quite pervalent. Isnt this something for concern?Sorry but that's just more flimflam.
Intelligent suggestion, folks stop trying to manufacturer fault or use poor reasoning to feel superior and just enjoy your own device and try to be happy for other people using theirs.
This goes for others here doing similar but vice versa re device. You will be better people for doing so.
We have two devices universally acknowledged as the best in their class and yet the thread has descended to such sad depths in order for users to appear superior. Is this really how you want people to perceive you ?
You owned 2 devices, so what? Doesn't mean you are better at discerning what is good or not.
