That's a personal desire. The context here was corporate buying and depreciation. Why would a corporation want to repair its computers, any more than it would want to repair e.g. its office furniture?

Because swapping a burned out power supply is 5min job while waiting for a [company] technician to bring that replacement computer can be a day+ several others to get the original back?

It boils down to how much the downtime costs. "Do it all in the Cloud" simply doesn't apply across the board.

Why wait? In most companies I've worked at (a few startups; IBM), if your computer isn't working, they take your current one and then hand you a spare out of a pile they have in a closet. The original gets sent for replacement, but you're already at your desk re-doing the documented onboarding process on the new machine.

How many large corporations buy macs for everyone in the company? Serious question... I have no idea. My hunch says; Not many.

Indeed. I've seen Macs as an option, and then you sort of get "developers can get Macs, VPs can get them, but others can't" as the TCO is - apparently - higher, and, let's not forget that, remote manageability is way harder than with Windows, which has stuff like group policies, AD integration, etcetera, all built in (the Macs I used at a previous big corp employer had some terribly hack-ish layered software to get to almost the same level).

With Win10 and WSL (which I've been actively testdriving on my personal hardware) I'd be totally fine to get a Lenovo from BigCorpEmployer. For private use, I won't buy any MBPs anymore anyway for the same reason.
