Apple's own marketing images show tons of these displays side-by-side with one-another. And that makes total sense; the M1 Ultra can run four of them IIRC. Apple customers, especially big businesses, will buy multiple of these just for the sake of them looking good next to one-another. Not unreasonable.
But what's the point of having three webcams & microphones? 18 speakers? Its just needless cost overhead; not to mention, I'm calling it here, when these things start shipping we're going to get a Verge article or something of people with dual+ displays complaining about how the webcam selection dialog in Zoom/etc is confusing because they're all ambiguously named like "Studio Display Webcam (1) (2) (3) etc". I can see it now.
I think it behooves Apple to offer one of these without all the bells & whistles. Knock $200 off the price or not, I'm not sure that's relevant; but as a secondary display, the bells & whistles actually get in the way. Its not about being a cheap dumb commodity PC compatible monitor; its just about serving what their customers are overwhelming going to want.
