My iPad has a few (at least five) dust particles under the glass. They're off to the edges and not really noticeable. My iPhone has considerably more dust that it gathered over the last two years but that thing is also beat to hell and back! Anyone else with an iPad dust-under-screen experience? If you went to exchange it, how was that experience? Mine's from Best Buy and they've been good to me in the past concerning exchanges but I've never tried one for a dust issue.
