A few people seem unable to conceptualize the difference between a production studio and some schmuck editing video for their YouTube channel at Starbucks.
Back when the iMac Pro was announced, I was thinking to myself, on my, when the Mac Pro is finally coming, it'll be pricey! I didn't expect it to be a good value compared to the $3500 iMac, a mass-produced consumer machine, versus a video editing beast. Unless you're Linus Tech Tips or MKBHD, shooting with a Red, don't even worry about the Mac Pro.
I expected the Mac Pro to be $5000+, with about the same base config as the iMac Pro. It's more expensive, and even less powerful. But don't look at the base config, this only makes sense if you're going to load it up for video editing. It's a long-term machine that you can keep upgrading for a long time.
Something that was designed from day 1 for high-end studios will never have the necessary volume to be affordable. What's misleading is that in the past they've had semi-affordable (barely) Mac Pros, and now they seem to be out of reach. Apple probably hasn't communicated this clearly enough, but this is for pros who need 4 concurrent 8K RAW streams, and stuff like that.
Enthusiasts look at it, ouch, this is a grand more than what I expected, the base config is disappoint (yes it is). Apple probably should've introduced a $4500 edition with consumer-grade guts, but they're not that kind of company. They've already covered that audience with the iMac Pro.
The lack of an affordable modular system is disappointing, but if it existed, it wouldn't be cheaper than an iMac, and it wouldn't be cheaper than a Mac mini + eGPU.
