AirPods, Pro, Gen 1, 2 or 3? iPad, Air, Mini, or Pro, which generation? And for used ones, where does it say on those products which model it is?

Apple also sucks at naming and labeling things.

TBH those names are the good ones.

Which Macbook Air do you have? Today, sure, you can say "M1". But earlier models did not have official names requiring Apple themselves to describe them in documentation as something like "MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports)"* or worse, resort to the internal part number ("MPXQ2xx/A, MPXR2xx/A, MPXT2xx/A, MPXU2xx/A" in that case).

Not that "Sony WF1000XM4s" is anything to write home about either.

Yes, I'll admit I didn't use Apple laptop naming as an example because I simply can't remember how it works.

Related, I have two old Mac Minis here and I can't tell which one is the several years newer one without finding a tiny model number printed on the bottom of both, looking them up, and comparing the specs.

I for one have no idea what ipads are better than what other ipads. Is Air better or worse than regular? How does that relate to Mini, in Apple laptops Air was the smaller laptops, but now there's also Mini?

At least companies leaning heavily into number-based schemes tend to make models with larger numbers the fancier more expensive ones. Acme Frobnicator 6400 is generally a lot better than Acme Frobnicator 3000.
