Again with this pipe dream?
Why does the iPad need to be a "Laptop Replacement"? They are different tools for different use cases. You might as well wish for a microwave oven that is also a replacement for a wood fired brick pizza oven.
Besides, why would Apple even want to do this? They would much rather sell you a laptop AND a tablet. And BTW, a phone.
Personally, I have both a Macbook Pro laptop and a few iPads. One is not a replacement for the other. It does not need to be. It is not supposed to be.
It never will be.
"iPadOS is the weak link and the reason the iPad will not replace the MacBook as a whole. The power and speed are there, but the capabilities are limited by iPadOS."
It goes both ways. MacOS is the weak link and the reason the Mac will not replace the iPad as a whole. The power and speed are there, but the capabilities are limited by MacOS. Because the Mac UI - AND the Mac apps - are not touch friendly.
AGAIN, different tools for different use cases. Apple would be foolish to try to combine them. It would be an exercise in compromise and frustration.
