because it is Apple, it is acceptable to have bad and differend quality? buy a ticket and see how much luck you have?
if it was any other manufacturer, i bet, they would have been nailed... example, looks how much oneplus ones yellowish screen has got negative feedback even when people dont even has it. how about samsung? that would be like in heaven to bash it. but when it is iphone or ipad, it is ok and acceptable, because it is apple? because lcd, because, because...?
sorry, but all those pics looks awful and i bet they look even worse irl than a pic. and no, it is not acceptable - not even from apple. the price tag indicates a premium, high quality product, not a crappy product from the first lcd screen years ago... low quality, high price - nothing premium. yes it will sell, they always sell - apples marketing department has earned the xmas bonus on this year too... but it is all just hype...
saying that it's all fine it is like pissing in your own eye and trying to justify the money you just spent.
will i buy air2? not now, im going to wait couple months if they tweak it secrectly (again)... if not, im going to skip this one... there is no apple stores here, so i cannot just go, buy and return. only retailers, and they dont accept returns, so i should always use a warranty, send it to apple, wait their response and so on.. if i cannot go to a store, buy the device without fearing it may have a bad screen, i skip it. where is the premium? only in the price tag...
