All these tablets have a 12MP camera on the rear and a 7MP camera on the front, though the selfie cam on the newer models works with Face ID and offers more advanced effects (like portrait lighting and Memoji support).
Apple's support note also explains that plastic strips or "splits" in the sides of the iPad allow parts of the enclosure to act as LTE antennas. For the first time ever on an iPad, these bands are manufactured using a process called co-molding.
For those that don't really care how their iPad is made - a constituency which, let's face it, encompasses almost everyone - the executive summary is that the new cellular iPad Pro uses co-moulding to inject plastic into "precisely milled channels in the aluminium enclosure where it bonds to micro-pores in the aluminium surface". After the plastic cools, the tablets are then machined to create a seamless integration between the aluminum and plastic.
Apple says this "flatness specification allows for no more than 400 microns of deviation across the length of any side - less than the thickness of four sheets of paper".
New study recommends a daily maximum for dietary fiber intake
In 2015, the UK Scientific Advisory Committee on Nutrition recommended an increase in dietary fibre intake to 30 g per day. But it adds that for people with an iron deficiency, high levels of whole grains can further reduce iron levels.
The new design of the iPad Pro and the manufacturing method might make any bend in the frame more visible to the naked eye from certain angles. "These small variances do not affect the strength of the enclosure or the function of the product and will not change over time through normal use", Apple writes on the support page. Apple responded to these complaints by saying that the iPad Pro's unibody design "meets or exceeds" all of its high standards.
See their blog post in full here. "Our current specification for iPad Pro flatness is up to 400 microns, which is even tighter than previous generations", said Dan Riccio. If you're shopping for a 2017 iPad Pro you can pick from silver, space grey, gold and rose gold, which might be one reason why you would prefer the older model over the newer one. Instead, it feels as though Apple is yet again trying to sweep the entire situation under the rug and pretend that bending to a degree of more than 400 microns isn't happening.
Whether you get it as a gift or gifted it to yourself, there's a little bit of extra prep work to do if you've just gotten your hands on a new 2018 iPad Pro. The company completely ignores evidence to the contrary, however, such as the video by JerryRigEverything that showed a 2018 iPad Pro bending like a paperback book with minimal pressure.
It could be, of course, that your bent iPad Pro falls outside of these tolerances.
