Nice review

>  iMac Pro now has four (Thunderbolt 3) ports

And there immediately is the first problem with the iMac all-in-one design:  if you have four Thunderbolt 3 connections + USB thingies in and out ... + ethernet etc ...  the wires going into this thing will start looking mayhem on your desk, elevated from the back of the monitor. That's another reason why a modular design, like the R2D2 Mac Pro is just a better design for the pro market. You can have all the wires either on the floor, or at desk level to the side ... and just a single cable running to your monitor.

Why after designing the R2D2 Coke can Mac Pro with some modularity ... did Apple never offer any upgrades for it??? Why can't we buy new graphics cards for it ... on par or exceeding the performance of the graphics cards in the iMac Pro?  That should be easy to do!   I wouldn't turn up my nose at 20 teraflops of GPU.

Yes - a long way and the wrong way. 

You should note that it only runs on Mac OS 10.13 (High Sierra). 

That is not very helpful to me (I run Mavericks - the most recent version before Apple lost the plot with 'flat graphic design" trying to make the Mac look like an iPad).

Noob doesn't even know what a computer is. Throw out your doodle board, grow up and get yourself a Mac.
