Well...hmm. I had my Air for about 40 days. Today I went to replace the screen protector on it and there was dust under the digitizer. Ugh. I am within the 45 day Elite Plus window at Best Buy, so I took it in and exchanged it out. I get the new one back to my office and...air for it...THE NEW ONE has dust under the digitizer. So...back to Best Buy to exchange it AGAIN. Luckily, the second one was fine. After reading the posts on here and other sites...it really seems like Apple is having quality control issues with these new iPads.
