It very well may be that every new iPad Pro has tighter ‘flat’ tolerances than previous iPad Pro models. The difference now is that you can see it, and if you can see it, it can be photgraphed. Michael Simon exposes Apple’s gaslighting of iPad Pro:
If the new iPad Pro you got for Christmas is bent in the center, don’t bother booking an appointment at the Apple Store. Just return the tablet, because the genius at the bar isn’t going to care.
To Apple, the iPad Pro’s bend is not a problem.
Apple “announced” that isn’t going to repair or replace the affected models.
There’s enough photographic proof that a number of warped iPad Pros are indeed arriving in customers hands. But in the face of this mounting evidence, Apple hasn’t indicated that it will replace any of them. In fact, Apple seems to be actively trying to convince users that there’s nothing wrong with their tablets at all. Basically, Apple is saying these iPads are either a) not bent, or b) supposed to be bent.
