With macOS going to ARM, it'll be interesting to see if Apple creates their answer to MS Surface Book.
It’s a fun topic to think about. They seem to want to keep iOS/PadOS and Max OS X separate, so I don’t think this is part of their short term strategy.
The surface is kind of a crummy tablet, combined with an underpowered laptop with limited application support. I don’t think that’s the direction Apple is taking. 😂
