The iPad Air is in such a weird spot.
Heavier than the Pro, 60Hz, but more Ram in the M4 Air than the M4 Pro? It makes no sense. Who is this for?
Ideally Apple would finally do their Surface/2-1 with iPads, but Apple being Apple, rather sell an overpowered tablet, and a Mac laptop to go alongside with it
Some places even do a bundle "discount".
I can say they are used heavily in the construction industry for Autodesk Cloud to render drawings for field workers. Very resource intensive.
