A study from 2022 found that deploying Macs in the enterprise has a lower TCO than Windows. Mainly because they have to buy less extra software and they don't need as many IT staff to support them. Also, employees with Macs are more productive and do better on their performance reviews.
I don't see this mentioned there, but that Apple has largely ignored enterprise works out as a strength; other companies wrote and open sourced pretty good tools. That can result in tools that better meet your needs, and generally will result in a lower TCO.
Yes and by contrast Microsoft has been enshittifying the hell out of Windows in order to extract more and more money out of the corporations they have contracts with. They force everyone to use Teams, Azure, OneDrive, and Office 365 so that they achieve total lock-in and ratchet up the cost of the support contracts.
Microsoft is basically following the same playbook IBM pioneered in the enterprise: use a slick sales team to get your hooks into into the CEO, CIO, and other senior VPs in charge of IT in order to force all their crap onto the company by top-down fiat rather than bottom-up informed decision making.
Depends on the enterprise. If you're a 1 user to 1 device shop maybe. If you're an institution with shared devices...good fucking luck, be prepared to enter device management hell
