Too Long; Didn't Read
Apple has defended the idea that a single customer can benefit from owning both an iPad and a MacBook. The product distinction started blurring with the introduction of bigger iPads, accessories like the Apple Pencil or the Magic Keyboard, and more desktop-like features on iPadOS. The new iPad Pro will also include up to 16GB of RAM, which is the same tech specs as the newest MacBook Pro. The iPad could support dual-booting into iPadOS or MacOS (Spoiler: a terrible idea!) But this is probably the most unlikely future among all the possibilities.
