when the user needs/wants it to be is because Apple wants you to buy two separate products. There’s no technical reason for it anymore.
It’s for that exact reason that I won’t be buying another iPad Pro or MacBook. I don’t want to carry a laptop around with me all the time when I have the identical hardware with me already in an iPad. And there’s no point getting a faster iPad if whenever I need to be productive on it I have to remote into an actual computer with a mouse and keyboard attached.
Apple will get there eventually I guess, I’ll just wait. I expect because of the corner they’ve shoved themselves in, it’ll end up being neither a Mac or an iPad.
