A "$2100 5K iMac - 6 Core I5 3Ghz" is not a substantial improvement over my late 2013 MacBook Pro (2.6 GHz, 4 core i7), which can both travel to client sites and directly drive 2 x 3840 x 2160 pixels on my desktop displays. No new MBP's have been worth buying. The new Mac Pro is nice but crazy expensive in a configuration I'd expected to be buying in 2019.
