UPDATE 3:35pm: Well darn, the same pop just happened on the new iPad!!!!
I went into Stamford Town Center at 11 to see about my iPad Air2 popping noise. The place was mobbed but they took me promptly.
When an Apple techie called my name and asked me what the problem was, I explained, waiting for her to say, oh yes, we know about that issue.
Nope. She never heard of it, had not had any other customer come in with a similar complaint. I said Apple Forum had a long thread and even bloggers are talking about it! [see me, reaching to pat myself on the back]
After some discussion with the other team members, none of whom had heard of the issue, she came back and said she would exchange my iPad for a new one.
I had backed up all my data yesterday so once they handed me the new iPad, I was out of the store, waiting til I got home to restore. The snow was coming down pretty hard in Stamford and the roads were slick underneath but once I got north of the Merritt, the snow was next to nothing.
