They did that with the 12 and 13 mini, but it was the same story. In spite of the mini’s popularity in this forum, in YouTube reviews etc. it just didn’t sell enough. There’s a reason it was discontinued.
Mini's sold just fine.
Airs are selling fine too.
The problem is Apple having turned into "if every product doesn't sell CARGO SHIPS FULL times INFINITY!" they have no interest.
We're all worse off for so enthusiastically supporting such a lack of hardware diversity.
Having options to suit various user preferences is good for all of us as users.
So when folks dog on the Air, or dog on the Mini, or dog on the Plus ... it's really just doing a disservice to everyone, including the folks doing the denigration of devices they may not personally have an interest in at that time.
