I've been giving this more thought, and I actually think an argument can be made that the machine actually is a Pro machine - and that Apple overshot "Pro" and headed into "Enterprise Pro" by accident.
I was thinking about my workload, for example, while in a lab. Storage should be some sort of shared storage anyway, so the loss of internal drives isn't as big of a deal - the SSD only needs to carry around the OS, applications and other things that *aren't* shared.
If something needs lots of cores it'll get sent to a dedicated computational resource - be it a "scale up" mega-server that vastly exceeds the current Mac Pros capabilities, or a "scale out" cluster. Similarly, if something needs GPU firepower, it'll probably get sent to another dedicated resource.
What does that leave? A powerful enough workstation to drive multiple screens, support development and prototyping, etc. Which the new Mac Pro will be able to do well - though since all I need is "Does it work?" computing power from the GPU and driving screens, I might be pissed if I have to pay for dual FirePros.
So why am I miffed now?. Because that workflow is the workflow of someone with a huge amount of institutional backing in terms of their computational resources. A research university, a major company, etc? No biggie.
But right now, that's not me. I'm much closer to a solo/small-group professional, where adding things like a dedicated NAS or the like is a little silly - it's just my machine doing the heavy lifting. And in that setting, the new Mac Pro is a recipe for a nest of wires and pricey enclosures.
So I feel like the new Mac Pro hits "Prosumer" and "Enterprise Pro" well, but misses smaller firms and solo folks almost completely.
