I feel I very much should be in Apples target for a pro-machine considering my Windows workstation is a dual GPU 1080Ti machine (cost a fraction of an iMac Pro and outperforms it) I use for 3D rendering, animation and video editing. Yet when I point out it's terrible value I again just get told it's not for me and it's for people who edit "Marvel movies" for a living.
I mean the only real complaint you could have with their pre-Mac Pro lineup was it just didn't have any way to fill niches, everything had to be good for the 80% and not right for rest. Wouldn't it have made a lot more sense to target this product as modular enough to fill the rest of those needs instead of targetting it specifically at the highest-of-high-end blockbuster movie editors.
