The great thing about computers is that there are plenty of options to choose from. Apple hasn’t supported removable memory in iPhones since day one. If consumers really cared, android OEMs would have continued supporting it and grown market share. But the market has spoken. Most people don’t care (and one should note that android doesn’t officially support removable memory anyway).

The same follows here. If the Mac Pro isn’t a good value for the intended audience, that audience will leave the building.
