But it's cheap. Had it been priced at 1500 USD, and had Windows 10 instead of Android - well, at very least the pen wouldn't be so laggy, and there would be software. And then, perhaps, there would be something akin to haptic feedback for the keyboard.

My point is: if Apple would ever attempt to do something like this the user experience would probably be out of the ballpark. And if it couldn't hit it - they wouldn't sell it. See also: foldable phone craze. Counterpoint: I hate the Touch Bar.
