As always, read the whole thing, but this bit jumped out at me:
From a design perspective then the end product is clearly a Mac laptop, but it’s a Mac laptop that’s more tablet-like than any before it. From the small size, to the low weight, the choice of a Core M processor, the passive, fanless cooling system, and of course the choice of metallic colors, the MacBook pushes against the line that separates Apple’s laptops from their tablets.
