Just to let you guys know - I‘m going to return (and
not get a new one) my 12.9“ LTE model in January because of the bend, even if it is not that obvious. If we pay 1.000 $ /1.000 € + for a device I don’t expect but REQUIRE those devices to be of high build quality. Sorry Apple, was always siding with you. But those literally insane prices (iPad + ASK + Pencil) paired with this issue is a no-go (at least for me). One would think that they have QC and people who use prototypes in real world usage, so I‘m surprised this has not been found out and addressed earlier. We all know those high margins on apple products, so I’m confident to say that we can expect quality. TL,DR: Voting with my wallet, which others should do, too. Hope I can encourage them.

EDIT: had a chat with apple support yesterday. I asked the support guy if an exchange with a new unit was possible - Reply: only with AppleCare+ (which I understand). Next, I asked if AppleCare would be covering a bent iPad - Reply: Nobody really knows this as of right now, but it seems that a deductible would be due to replace those iPads. That’s what ultimately got me to the decision to return and not get a new one. Definitely
not going to pay for a (factory-) bent iPad on normal usage.
