There is the tinniest little spec on my Air's screen inside the glass that won't come off. I've never had an experience of going to the Apple Store and getting something replaced. Would this even be enough to get it replaced. You can only see the spec against a white background if you look really close though. And how would I handle it? Do I just go there and ask them straight up for another iPad and show them the spec or would they have to be the ones to decide without me asking for another one?
