So, obviously this is a product that was not made for you since you already have a display. Why do people complain about a product that was made for someone else's needs? If you need a modular Mac, Apple is working on one and you can get it next year.
Bummer that Apple took so long to realize that they messed up the Mac Pro design, but that doesn't mean that this machine isn't going to be just perfect for a large number of pros.
Actually, the base model iMac Pro is targeted precisely for users like me - Capture One Pro uses multiple cores effectively, and it also uses GPU acceleration better than any other RAW processor for photography. I can easily use two displays, but like I said, there's no way I'd pay $5,000 for that machine when I can build a better one for far less.
Apple is charging $200 for an 8GB 2400Mhz ram upgrade on their new regular 2017 iMacs (from 8GB to 16GB). I can get 32GB 3000Mhz for $275. To go from 8GB to 32GB in a regular 2017 iMac, it would be a $600 upgrade. ...And the fact it's an closed system (beyond the ram) is worse.
Apple also crippled the 21" iMac - wish they'd have offered at 4.2Ghz CPU in that little thing, along with an option for an 8GB GPU. That might have been my perfect machine for a dual display set-up. But nope!
I never said the iMac Pro isn't going to be perfect for a large number of pros. I'm saying it's overpriced, even for those large number of pros.
As for the Mac Pro....I've already been waiting 8 years for a worthy upgrade. If the iMac Pro is starting at $5,000, it's a fair bet the Modular Mac Pro will start somewhere in the neighborhood of $6,000 without a display. It won't start less than $5,000. I'll be surprised if it starts at $5,000.
If you don't need anything more than a 4 core machine, then the 21" iMac is probably perfect. If you're going to use any of the iMacs (regular or Pro), it's just flat out over priced. By a long shot. And waiting 3 years for a modest speed boost with an Intel chip that'll be outdated in three weeks... ?
I was very much like most Apple users, as I've been an an unapologetic Apple fanboy for 35 years. But over the past year, as Apple continued to ignore their "pro users", I began looking for other options. I was really hoping to be wowed today, and perhaps have a little bone thrown to the pro users for waiting this long, like drop that entry level iMac Pro price by $1,500, (and drop the price of the 2017 iMac by $500), and I'd be all over the Pro.
But yeah. Please don't tell me the iMac Pro isn't for me. It is. It's just too freaking expensive.
