Is there anyone who has exchanged a new ipad because of the heat issue? I thought my ipad was normal, until I tried the ones at the apple store, which are definitely a bit cooler than mine when plugged in for a prolonged period. I want to show the genius the problem, but it will required the ipad to be plugged for at least an hour. Will they just accept the old one, or will they make sure to check if the problem is really there? Anyone with previous experience? Also, for exchanges, will the 14 days period reset or will it carry on from when I first received it on the 16th?
