My Apple Store experience was that I carted my iPad in and compared it to the display models. To my eye, my iPad looked darker and to the yellowish hue as compared to the pure whites on the display ones. I was told by the Apple people there not to compare to the store models. smh
They also took the thing to the back and a "genius" checked it on some sort of computer back there. They claimed all look "normal". I just know what I see.
In any case, I was going to swap, but they had no 64GB Verizon iPads. I might go by there on Friday, but I fear a circus of going there over and over again, hoping in stock.
I might pursue doing the swap through online / shipment, as I had it shipped via FedEX. I'm still holding out hope, I guess, that this thing will "fix itself", but I know this is very unlikely.
This was at the San Tan Mall Apple Store in Gilbert AZ, for what it is worth.
Just sharing my experience today.
