One major headache with the previous Mac Pro was the size and weight as it was difficult to rack mount and weighed a ton! Now we have the new Mac Pro which is small in size but expensive.
I would like to see a more accessible Mac Pro (lower spec and cost) or a updated Mac Mini with a discreet GPU for people who need dual monitor capability for sub 4k video editing and live work.

Update: OWC confirms the new Mac Pro processor can be upgraded ... but can we downgrade the spec to make it a more accessible price?
