Very sad day. In the first moments, I thought everyones wishes had come true, and they bring back the old style Mac Pro back, with a redesigned housing. But the old Mac Pro had started around 2-3k, so while never cheap, not out of reach of an enthusiast user. While the specs of the new Mac Pro are certainly impressive, the price is just out of the range of all private and most professional users. Not sure why Apple refuses to sell a machine which just allows to put in a normal desktop graphics card.
Also: they are selling a "Pro" desktop Mac without real mass storage? Just 4T of SSD? (Of course only available at Apple prices). The old Mac Pro had a lot of storage slots, both for 3.5 and 5.25 inch drives, but the new one couln't house at least a couple of 2.5 inch slots as well as NVMe slots?
Magnetic drives perhaps not, but I was mostly thinking of SSDs. But indeed, if you can use some of the PCIe slots for storage, it would probably be ok. Still a too large gap between the Mini and the Pro.
You have to bear in mind the target market - notice that it has dual 10Gb Ethernet, and that many users will be using a NAS. There are a shedload of PCIe slots there too for more storage.
