It is clear from the photos that these out-of-the-box bowed iPad Pros are like nothing seen before. Apple even admits that some are coming out of manufacturing in a bowed condition.
Apple's Dan Riccio's statement doesn't directly address the issue. He is talking about the standards and tolerances but NOT saying that those bowed iPad Pros are within those standards. He is leaving the connecting of dots as an exercise for the reader.
The only admission I've seen from Apple is Ricio's claim of a 400 micron standard. If you have an admission from Apple that iPads are leaving the factory without meeting this standard, post a link.
