And employers love them because if people take them home overnight they only need security / insurance for peripherals. The only fixed PCs I still see in offices are low cost / bulk Dell machines only good for office work or thin clients, and even those go back ~15 years now, at a bank that already had relatively tight security.

I wish I could have a job where I work on a desktop machine and could just leave things at the office when I leave for the day. Alas.

What are those places? Do most people have multiple residences? Or do they think they might need it, and in practice never do?
