The bigger problems Apple has are their enterprise device and user management, and the fact that many businesses are still reliant on Windows-only software.
Most companies I’ve worked for buy machines that usually aren’t much cheaper than Apple equivalents, at least in terms of MSRP, despite the quality often being worse. My work-provided 2022 HP Z-Book 15 is more expensive as configured than my personal M2 14" MacBook Pro, and is still a shittier machine in just about every objective (and subjective) way I can think of. This is because enterprises typically buy business class laptops like Lattitudes and ThinkPads rather than lower cost (and less durable) consumer oriented machines. That said, it is not uncommon for IT departments at large enterprises to pay well under MSRP for these machines when buying in bulk.
None of these problems are really dealbreakers for a consumer-oriented file system in 2023. Not even ext4 supports CoW. Now that everyone boots off an SSD, things like file fragmentation no longer matter, and most of NTFS’ continued slowness has more to do with Windows itself than the actual file system.
ReFS is Microsoft’s new file system meant for more advanced use cases. It supports many but not all of these advanced features. Starting with Windows 11, you can actually boot off a ReFS drive, though I’m not sure that is a recommended configuration.
