The iMac Pro is awesome, but the lack of target display mode makes it use a lot of space that can't be used with anything else. Older 27in iMacs were awesome for that - personal Mac for home, use as an external screen for work when working from home, or as an external display for a gaming PC.
Where are we supposed to place the sacrifices to the gods who will keep all of our 5-7 year old Macs alive until the new ones come out?
