I agree with this but I also recognize that if that separation is successful and we have the 'user' Macbook and the 'developer' Macbook, the latter may become more expensive still as it will have much lower volumes of manufacturing.
Shouldn't the developer be in the Macbook Pro camp?
I think iPad Pro, with iOS 11 has shown what tablet is really capable of. And we are only just getting started.
Hence why I wish Apple will just leave the Mac as a PC. A PC with macOS. Stop dumping it into Appliance, give more choice and better flexiblity, heck even iPhone has more choices and model then the Mac.
