It's really not. Apple's phone margins have been as high as 30-40% per-unit, it's likely that they make at least ~$80-150 per Macbook Neo sold.

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.
