I'd buy a $1500 Apple monitor if for no other reason than the fact that Apple would actually put a decent set of speakers on it¹, like they did with the Apple Cinema Display.
¹It's not clear to me if the Pro Display XDR actually has speakers at all, but its audience can be expected to buy a set of high-end speakers too, whereas a monitor aimed at actual users would need built-in speakers.
