I'd argue that moving from "iPad Air 2" to "iPad" is a step in the right direction, but I agree with your sentiment. "iPad Mini 4" is the most confusing title

I'd argue that moving from "iPad Air 2" to "iPad" is a step in the right direction, but I agree with your sentiment. "iPad Mini 4" is the most confusing title in the lineup currently, but I expect them to eschew its version number as well at some point. I prefer the "Mid YYYY" style of versioning Apple uses on other products.
