These are not better names. If Air or SE are confusing or redundant then why is Pro or Ultra still acceptable?
Additionally, Pad is a terrible name and why is Pad 10” better than iPad Air? It doesn’t seem clear that it is an improvement.
Apple actually has one if the more straightforward naming conventions, the likes of Microsoft, Nvidia, Intel, and AMD do not, or at least don’t until you learn their specific nomenclature.
