While I have not yet decided whether to request that Apple replace my machine - it has the yellowish tint on the bottom third of the display - I am more than a little dismayed by Apple's approach to quality control and resolution for this particular issue.
That a substantial number of users who are justly unsatisfied with a key element of their premium product are uncertain whether to engage in a game of roulette with Apple, ie: trading in a bad screen for the "potential" of a better LCD, while at the same time wary of other manufacturing defects which may well be present in the replacement laptop, suggests a pretty shameful business ethic on Apple's part. Sure they will replace a DOA for the first 14 days, with what: another DOA. That's not thinking differently, that's thinking greedily.
If the screens are dodgy Apple should d**n well stop the f*****g assembly line and fix the problem; offer replacement lids for anyone who feels that their $2500.00 computers are not worth the price of admission. At very least they should not passively hand out replacement machines from the same gimpy stock in the hopes that discerning customers will eventually be frustrated into submission; time to own up to the booboo Apple!
My personal feeling is that a LOT more than a few of these new machines have this particular issue, but that many people just do not find it a bother (or would find the Apple-cum-Vegas routine more of a bother), or are altogether unaware of the problem.
Apple makes some great products, there is no contesting this. But there is a certain cavalier way that they seem to approach reconciling manufacturing errors; I have read about this with batteries, heat, former iterations of the MBP screens, etc.
I really like my new computer, save for this one aspect of the LCD. I watched and waited over 18 months to see Apple finally release a build that was spec'd the way I needed it.
I really like OS X, but to be left with the itchy feeling that apple knows they have you over the barrel for the priviledge of using the one and only is distasteful.
