I see no point in buying it now, for me it should be abble to replace a 5 to 7 year old Mac Pro.
So it needs to mature, 32 gig ram, at a price that doesn't make me follow these logic
for that price I better buy a nMP, but for that price I better go windows ...
Mac Pro's weren't that expensive from 1,1 - 5,1 , they were, but not much, dual xeon PC's aren't cheap eather ...
Just happens now workstation PC's are much cheaper or much faster.
I also want to see what happens the next months, even maybe year.
The first Mac Pro came some time after the first intel macbook pro.
I do think I would switch to windows if it would just be Imac and these touch bar Macbook pro's.
And the last surface really got my attention, Microsoft seems to have a much better vision of where they want to go with that. Surface pro - surface book - now surface studio.
I like they put the ipad pro and macbook pro in one machine, much more interesting than a touchbar.
Apple feels more like it just want to build a prison around you for a vision, and making prison life harder.
I also don't like the fast OS X update's,
just canning old mac's and at the same time not releasing new one's.
It's annoying in a workflow, OS X was about winning time, but I spend a lot more time on information now, update this, update that, will it work, better keep that mac on Mavericks for performance, blablabla ...
