Just my opinion, but this will be a low production product—no where close to the Mac Books or iPhones.
I’m a exclusize Mac user and the Mac community are in meltdown mose over the price, so not many users of these devices at all.
The 2019 Mac Pro is not intended for consumer usage, it is in all ways designed for the professional market who will use it for production and making money. For them, it is far more economical than the competition.
Another good example of this is Apple’s new XDR 6K Reference 32” monitor. At $6000, it also is not intended for consumers but for the professional production market. It competes against Sony’s 31” 4K BVM-HK-310 Master Monitor, which has a retail MSRP of $43,000! . . . But the Apple actually has more features and better specifications than the Sony competition. Apple will sell tons of these to the professional movie and TV producing editing and FX market.
A fully configured new Mac Pro can drive SIX of these monitors for those kind of purposes. . . And produce 56 Teraflops of computing power. No consumer needs that.
