I've read several reports of iPad minis with bent bodies. Now I'm facing the same problem for the first time with my own iPad, though it's an iPad Air. I can assure you that I've done nothing wrong with the iPad in these less than 2 months of use. So I'm not completely sure what the cause is. I just discovered how bent the body is today, though I suspect it was a progressive problem due to the thin and light form factor and the hot weather (sometimes the iPad got kind of hot during normal use). Have you seen anything like this on an iPad Air? It looks really bad.
