I am the weirdo that spent $7,000 on Apple's new Mac Pro and after a month of testing it, I think lots of people are missing the point. Check out my full review on Apple's most capable computer. https://www.youtube.com/watch?v=tucbrkWxmNA
Fair points! I know almost nothing about that industry so this is very good to know. I suppose they are all effectively one cable thunderbolt devices that sit in server racks.
If PCIe cards aren't helpful anymore then I suppose the only remaining benefit to the Mac Pro is that it's rack mountable? At that point Apple could just bring back a 1U or 2U chassis and be done.
