In computing "Pro" is not the opposite of "Consumer".

Putting aside the fact it is a marketing label, "Pro" usually means "designed for work" while "Consumer" (in this context) means "doesn't need a special environment".

In computing the distinction is primarily noise, power and cooling requirements.

If a computer is designed to use home power and is quiet enough to use without annoying people and doesn't require specialist cooling then it is a consumer device, even if it is used for work.

Apple's use of "Professional" is just a fancy alias for high end or premium, it in no way indicates anything about being "for professionals" (most extreme example: "professional" iPhone models)

Hence why they had to make up the "Studio" brand for the workstation market, because they'd already fully removed any meaning from "Professional"

Yes?

at a 100k$ you're not buying apple products to be limited by the 120gb/s thunderbolt port.
