The hard part is the GPU architecture. Apple Silicon was designed with a laser focus on raster efficiency (similar to AMD's GPUs) which makes a lot of sense for highly mobile hardware, but is a crippling mistake for high-performance compute. Apple's largest Ultra chips are hamstrung with SOC-tier GPU performance, their highest-end desktops are outperformed by Nvidia's laptop offerings. Apple has to find a way to scale upwards without imposing too much architectural strain on their cheaper hardware like the iPhone and Macbook. Nvidia has already solved this issue; full CUDA compute stacks are usable on extremely cheap GPUs like the Nintendo Switch's Tegra SOC, or the Mac Mini-sized Jetson boards.
In terms of "who needs to redesign more to address the market", Apple has a lot of technical debt to unearth before they catch up to Nvidia. And if they do catch up, Nvidia will still support Linux and other differentiating features that Apple refuses to implement. It definitely feels like Nvidia is closer to a winner with the Spark than Apple is with the Mini or Studio.
Those Macbook Neo users would be very reliant on Apple intelligence, enough maybe to pay for a service with it. I think Apple's much happier going this path.
If it's an "or," absolutely. But if it's an or, they should be prioritising Macbooks over the Mac Mini Doug Brooks is discussing.
When we breach the "and" of memory supply sufficient to allow for more Mac minis (and Mac Studios), I think it would make sense to consider relaunching Xserve (with new branding, of course) as a consumer/small business product.
The writing has been on the wall since 2019. Apple doesn't like the old way of computing, their goal is to expand the ecosystem by prioritizing install-base and then pushing first-party service offerings like they did with the iPhone. And like they did with the iPhone, Apple is great at ignoring power users to focus on features that make them more money.
You may be waiting a few decades for this type of product, memory supply be damned.
At the $150 mark (which is probably accurate factoring in lifetime service spend), that's a $10,000 minimum return on the 64x Macbook Neos. Apple can charge that type of premium on consumer hardware, but they're in no position to command $10,000 margins on professional hardware. They're not Nvidia, Apple has always been LARPing as an HPC vendor.
Now that the Mac Pro is depreciated, Apple's plan to pivot to service offerings seems set in stone. That's the "want it all" attitude they've adopted with the App Store.
