I've always looked at the current MacPro and Pro Display XDR designs as unnecessary and, indeed, impractical as actual "working computers"...the cheese grater design, while an innovative (to some) "work of art", is merely an invitation to environmental (atmospheric and living) ingress that will promote device failure. Keeping dust and bugs away from internal circuitry is a real concern.
Too much emphasis and cost on outward design and appearance vs providing the best solutions for performance and longetivity leads to products that serve niche markets vs what Steve Jobs set out to do and provide "bicycles for the mind".
Marketplace failure to provide competing 32" 6K miniLED displays to compete with the Pro XDR has only served to allow Apple to keep this product in production as long as it has and at the prices it commands. As a result, creatives looking for HDR mastering monitors have been left in the lurch waiting for tools to get on with their day at price-points that make more-practical sense for their budgets.
The technology for 2000-nits HDR displays has existed for the better part of this passed decade and the consumer and creative HDR market has been ignored in two parts...one, by the one company with the creative drive to push that marketplace forward and, the other, by an industry that is more than happy to continue to sell cheap plastic boxes of regurgitated twenty-year-old display technology.
IMHO, a 6K 32" XDR iMac should have arrived with the advent of Apple Silicon and, for that matter, an 8K 42" XDR iMac, as well.
Next week I will be attending the BILD Photo Expo in NYC and be coming home (I expect, if they're in stock) with an 8K/HDR-shooting Nikon Z8 with only one prospect for getting any work done with it...a 4-year-old 32" 6K mini-LED 1600-nit HDR monitor in an unnecessarily housed-in-an-aluminum-art-frame at a cost that makes zero sense for my needs. Well...at least, it's more than the PC-side of the world has to offer right now. Oofah.
