Earlier quoted context omitted.
I know it's semantics, but Apple has never actually marketed their Air products as lighter than their Pro counterparts. The 11" variant is ~460g.
What are you talking about? Air literally always meant thin and light. Now they're treating it a premium product between normal and pro instead (see iPhone Air too)
If they need a mid-tier brand between entry-level and Pro, just call it Plus. The iPad Plus would make a lot more sense.
