99% of Apple’s revenue is generated by customers who couldn’t care less about a new (or previous) Mac Pro. It’s likely few if any Apple salespeople even carry quote for Mac Pros the volumes are so light. Most Apple customers have never even heard of things like PCIe and can’t even imagine the types of workloads and datasets that would require +1TB of memory, $x,000 graphics cards, or external RAID storage. Just take a look around here, you have people arguing/debating/discussing whether 8GB of RAM is sufficient for serious work, concerned about the SSD throughput on 256GB SSDs etc. The vast majority of Apple’s customer base and revenue wouldn’t even register the loss of a Mac Pro. It may be a black eye for Apple with the subset of pros that still care about a Mac Pro (I care btw), but of the billion-plus Apple devices in circulation and in landfills, how many are Mac Pros from any/all eras? 100,000? 5M? Apple’s market cap, margins, and huge pile of cash are enough of a halo. If Apple kills the Mac Pro, it will be a painful end of the road for some of us eternal optimists, but within a year, no one will even care or remember, except some scattered enthusiasts holding onto prior models until - at least in the case of select 7,1s - the wheels fall off.
Long live the 6,1!
