Amitface: I am in complete agreement with you and your intelligent motives for starting this thread. Many people are now saying in the other threads that every LED MBP has the bottom 3rd yellowing issue, the only difference is that some people don't notice or aren't as fussy. So your logic is to ask people who have been sensitive enough to notice in the first place (to have sent it back) to confirm if they ever received a non yellowed screen. This is a different negative affirmation than was received for the multitude of other less cunning questions which simply asked if you have had a problem with yellowing in bottom 3rd of screen.
I also fully support your rationale that you required a new thread in order to appeal to those who no longer visit the bloated "yellowing" thread.
To everyone else who has not aided in answering this valuable question, and has instead complained about the amount of chaff filling these threads, I have news for you: It is YOUR posts which are the trivial waste of space you complain about and now greatly contribute to the fragmentation of this once focussed topic. If questions were left to be answered specifically, then there would be no need to complain. I'm speaking specifically now to you ScottDrummer since you were first to contribute criticisms with your dulled analysis as to the necessity of such a thread. I apologise if I am further fragmenting this thread, but I wholeheartedly agree with the validity of amitface and his initial decision to post this way. Now please, can we have some serious people answer the original question as asked?
