Apple does not upgrade the Mac Pro but the iMac. That is fine with me but why such high specs machines especially the iMac Pro has a max screen size of only 27"? I would imagine that users who use such high end machines would need larger screen size. Getting one of these machines and purchasing another 30+ large screen display is expensive in terms of desk space and money. I would prefer a headless desktop or a MBP with a 32-40" screen.
