I'm on my 3rd iPad Air. All have had some sort of issue. Three of them have had color uniformity issues and one of them has had speaker issues. I made a thread a while back complaining about the Air's speakers thinking that they were a definite downgrade from the 4. After getting feedback and realizing that I had a bad unit, I swapped out. The next unit I received was infinitely better and clearer. The first one I had sounded muffled and faint and very hollow. I've actually noticed a speaker difference in all of them. The latest one I have now has the best speakers out of the three but the screen is the worse. There is a noticeable yellow -> blue color temp shift on these screens! It is even more noticeable from the bottom left corner. I took a pic highlighting this. It's obvious that the right hand side is far more yellow than the left. I wouldn't even care if it wasn't so noticeable while reading. While watching movies or looking at graphic rich content, I don't notice it at all. I am returning and just getting an 11" MBA. I don't know what is up with Apple and their QC. I don't care if a screen is more yellow or more blue but when there is a shift it just isn't acceptable at all to me. Why is it they can produce perfectly fine screens on their laptops but iPad screens just never are produced with the same care? The Nexus 7 is a much cheaper tablet and has none of the flaws I've seen in iPads. I know these threads are a broken record by now but I'm just disgusted enough to vent via new thread. It wouldn't be such a big deal if Apple didn't charge a premium price for what is supposed to be a premium product.
