To succeed as workstation you need to cater for corporate and there Apple is weak.
Apple has ensured that by the complete lack of continuity in the Mac Pro line since 2012 - however, there's a chicken and egg question there: did that happen because Apple was incompetent, or was it because they realised it was a shrinking market (even in the Windows/PC sector) anyway?
In a market where sheer computing horsepower is king, the ability to bolt together custom systems from commodity hardware and still have a huge software base is going to win - a marginally nicer UI, slick iDevice integration and great battery life isn't going to cut it there. Apple is going to be dependent on users who are somehow locked into a MacOS workflow, who are going to drift away one by one as they finally make the break and migrate to the cheap hardware.
Is the Mac Studio, effectively the Mac Pro?
What is a Mac Pro?
No, Apple haven't made a "true" Mac Pro - a tower system that took over where the iMac & Mini left off - since 2012
No, the 2019 Mac Pro was the only "true" Mac Pro
The 2019 Mac Pro
wasn't a true Mac Pro - it was some sort of "Mac Ultra Extreme" that cost 5 digit dollars for any configuration that made sense. The true Mac Pros were the Trashcan, the iMac Pro and the i7 Mini.
The Mac Studio is the spiritual successor to the Trashcan Mac Pro.
The Mac Studio is just the Mac Mini Pro...
The 2023 "Mac Pro" is really the "Studio Ultra PCIe Edition".
No, a Mac Pro has to have expandable internal storage and PCIe.
No, a Mac Pro has to have NVIDIA GPUs
No, a Mac Pro has to have <my personal favourite feature>
No, a Mac Pro has to have "Mac Pro" written on the box.
...and so on, until you get to:
No, the Studio has seen two major updates in that last 3 years, it can't possibly be a Mac Pro until it's been neglected for 5-6 years...
What I would say is that if you pretend the 2019 MP didn't exist, the Mac Studio is the obvious successor to the Trashcan and the iMac Pro, which is clearly the way
some at Apple saw the Mac Pro evolving.
'pro users', but honestly these days, what are those.
"Pro" users need their machines for paid work & can justify paying a bit more. That's all.
"Pro" products are slightly more powerful than the products that don't say "pro". That's all.
A Pro user will use a Walmart M1 MacBook Air if it gets the job done.
I can probably buy "pro" toothpaste and shampoo in the supermarket. The makers are *not* targeting those at dentists and hairdressers.
