An iPad Pro and a MacBook Air have the same core hardware - even the same M1 CPU. Add a keyboard and they look really similar except that the iPad has a touchscreen!

But there are lots of hybrid tablets and touchscreen laptops. What makes the iPad an amazing device for me is its outstanding software library (e.g. Procreate) and the Apple Pencil.

I could certainly imagine Apple bringing its Pro apps - notably Final Cut, Logic, and XCode - to the iPad. But I can't imagine Apple opening up iOS any time soon any more than I would imagine Nintendo opening up the Switch.
