So I can get an
iPad Pro (128GB) with pencil and keyboard for $1217 (USD)
or All with keyboards and with more storage that is expandable:
MacBook Air $899
MacBook Pro $1099
MacBook $1299
MacBook Pro Retina $1299
Hmmm, something seems wrong with the pricing model...
Still, it will sell and sell. And the reason is because people have different needs and maybe do not see the comparison the way that you do.
They might have the following reasoning behind it: I don't need a fixed keyboard and using my Cintiq on the go is a chore. The iPad Pro with pen suits my mobile needs better than a laptop with all the peripherals needed.
