I do know people who no longer have a personal computer, and use exclusively their work-issued computer. I wonder how common that is.

Around 2005, my employer at the time did a refresh of our it equipment, replacing all the cheap stuff we had been acquired with. They asked everyone to say if they need a laptop, as desktops were the default at the time. I said I didn't, and was surprised when he turned out that almost everyone else said they did. Most of them didn't really need one, and presumably were planning to use them for personal stuff.

The company was a bit salty about this as laptops are more expensive, but they got them. And of course the company befitted, as that was the end of a clear separation between work and home. You have your laptop, you can answer email and attend meetings with people in other time zones. Before, it was easy; work stuff stayed on work computers and those didn't leave the office when you went home.

Not much around here, while it is tolerated for accessing something over the Web, the cyber security trainings explicitly mention being a possible way for job termination when something goes wrong, after installing anything not cleared by IT.

May be the opposite, but BYOD is a thing and has the same result, security-wise…
