I agree with the sentiments echoed by many: Yes, regular customers don’t care, but we are here, and we don’t analyze iOS devices in a vacuum. In a vacuum, the 10th gen iPad has many advantages when compared to the 9th gen. Looking at it in context, it’s not the best value, currently. The Air 4 is a better value, the 2018 Pro is a better value, and its drawbacks make it so that it doesn’t make a lot of sense if looking at Apple’s released products. On the lineup? Yeah, a better 9th gen with the annoyance of the Apple Pencil adapter for more money, makes sense, but when you add the Airs and the older Pros it loses that advantage.
As Apple still sells the 9th gen, arguably that’s a better price-conscious buy, if the user doesn’t care about the screen differences (or can tolerate them). Note that I didn’t say that it is a bad product, only that it isn’t the best value.
