I'm a pro user, and I'm complaining about the price. Not all pro users can afford $5,000 workstations - that's literally a closed ecosystem for upgrades.
Considering I already have a perfectly good NEC display for my work, I don't need a 5K display. So if I want a new Mac that's worthy of an upgrade over my 2009 Mac Pro, I have to get the 5K display - regardless which 27" version I purchase (pro or regular).
I can either spend $3,300 on a new iMac with the 8GB AMD video card, or I can buy a similar spec'd PC with the same 8GB AMD video card, an m.2 boot drive and a 500GB SSD active jobs drive, overclock the 4.2GHz 7700K CPU to 5GHz, and skip the display, for $1,900. ...And I can upgrade the ram, GPU, CPU, drives, et al, as needed - instead of buying an entirely new iMac. ...which likely won't come around for another 2 years, and it'll be a modest spec bump anyway.
OR! I can build an 6-core (overclocked to 4.5GHz) with two M.2 drives, 32GB RAM and a 1070GeForce GPU for $2,200 - again, skipping the display. ...btw, that $2,200 leaves a LOT of room to reach $5,000 to buy a sweet display for photography processing if needed. Almost forgot, add $200, and and at the end of July, It would cost me $2,400 for the same set-up but with an 8-core 28 PCIe lane Skylake X chip, which (allegedly) can be safely overclocked to 5GHz.
So yeah. Us pros have every. Freaking. Right. To complain about the $5,000 price.
Cheers.
EDIT: Forgot to add - the Kabylake chips in these iMacs will be outdated at the end of this month when Intel releases the new Skylake X and Kabylake X chips - which are "Pro chips". So there's that. LOL
