Every company I've worked at will not allow me to leave my laptop at the office. They all claim it's something about the office not being safe from theft in some way or another. My bet is it's just a lot easier to get people to be constantly connected if they have their work laptop with them at all times.
Dr is the big one I've seen, from an ops side. If anyone with a laptop that can work remotely takes it home and the building burns down, well your company can still mostly work until replicated.
Not my idea, not my decision, but someone must have weighed the costs of laptop w/docks vs desktops and risk of one site going offline for a few weeks and decided it was worth it. For a finance company, I guess those days could carry a lot of cash flow if not regulatory risks as well which could help push the laptop argument.
I really liked the model laptops we were deploying and how the push allowed us to clear out some real old desktops. It was helpful to be mobile but I did keep an old desktop at my desk with tools and more that I could remote to from another desk or from home to do things on site.
