Because if the iPad can run macOS I will not buy a MacBook anymore period. Apple knows it.So focused on creating a keyboard for iPad, they never thought to just add Apple Pencil support and a Touch display to a MacBook.
"But iPad and MacBooks are two different products", I hear the defenders say.
Yeah, look at iPad Pro with the latest Magic Keyboard for iPad and tell me how it's not just a MacBookrunning iOSthat isn't allow to run macOS? Or why you can't use Apple Pencil on a MacBook? Why?
All these nonsense, beyond over-priced accessories for iPad is on such an extreme level of fence riding that you'd almost think Apple is out of ideas for iPad.
