I don't question the security benefit. I think you're absolutely right that the users always come first. The production system and its data was never running inside the company network and is protected additionally.
I feel it'll be a loss of usability since they want to have a one-size-fits-all laptop. The model I've seen is noisy and a bit heavy. Suddenly having to carry one every single day irks me a bit. Having to (un)plug monitors and periphery at home is going to be additional effort (but explicitly allowed). Not saying it's not worth it (and somewhat complaining on a high level), but it is a loss of comfort.
