Not to worry, Apple adds a couple hundred dollars to each of out devices due to OCD caused by this forum. It is just built into the price.
LOL
I took back a Mar7 preordered iPad that had some black spots under the glass but everything else perfect. This iPad I'm typing on seems to have some slight yellowish compared to my iPhone at least, and especially when slightly tilted, but not sure if this forum is causing me to see things or not. Ahh, I guess if Apple is just going to give me new iPads until I'm 100% satisfied maybe I should go get a different one?
