So I don't know who you're talking about when you say "this is for 'Pros', because at the moment, it's really just for rich people.
You are undoubtedly correct, but at least the same time, only rich people can afford high-end tech. This monitor simply has no analogues, and it’s priced rather competitively.
Sure, i’d love to have thing on my desk and I’d be happier personally if Apple instead went for a more reasonable mid-range device, but they are trying to reconquer the absolute top, which I think makes sense. The hardware looks more than impressive, the price is perfectly fine for the target industry and we normal folks will just have to wait until micro-LED tech becomes more commonplace.
