Are any of their products even new anymore? It looks like the MacBook Air hasn't changed in four years!

It hasn't - they don't intend to update it either. For now, the newer Macbook and Macbook Pro 13" (without touchbar) are intended to be the 'newer' Macbook Airs.

To ask 'are any of their products even new anymore' is a bit odd though.
