I posted what's below in the gadget thread... long story short, no Apple never wins on price. However, having built in 10gb Ethernet, and TB is actually pretty amazing. I do think, that they set the bar very low for Microsoft to respond. And I'm sure that they could build a studio PRO, for 5k, that will exceed apple's new Imac Pro.
a "pro" alternative, just add monitor and/or webcam
Does not have thunderbolt, or 10G Ethernet. You can, however, get 10gb ethernet on single socket matx motherboards, and Thunderbolt will show up everywhere since Intel got rid of the licensing fees.
Further, I would expect to find both of these on motherboards based on the unreleased x299 chipset before you can expect delivery of the new shiny black iMac.
I would have been more impressed had they just released a new mac pro, not an iMac Pro. I would also not expect their unit to be able to sustain workloads for extended periods of time at the maximum TDP since you can't defy the laws of thermodynamics. But it's an improvement over their existing options. It's not the revolutionary response that I was expecting after the surface studio.
