Considering I don't have access to all Ipad Air's that would be a little difficult for me to know. This is the entire point of the thread, people are here discussing the problem working out if this is a first batch issue, a certain manufacture issue or if all Airs are like this. Coming in and saying "Well just ignore it" or "You're standards are too high" is basically adding nothing to the conversation and giving no extra information. How are people supposed to know if it's an inherent problem with the Air screen if they don't talk about it with other people having issues?
Most people here are returning it and trying out replacements and then if it isn't sorted going for a refund but it's always sensible to get other people with issues experience to help in making those decisions.
I'm sorry but I think it does add value. Because you have three courses of action including: exchange it, return it, or keep it. I've been in the 'exchange it' loop and it wasn't pretty. So my point is to deeply think about 'return it' or 'keep it' before entering into the 'exchange it' loop. I'm sorry if that's not the answer the majority of the people in this thread want to hear.
