Enterprise hardware has companies that your company can call to get support when things go sideways, if they're using a rack full of 5 year old Thinkpads then they're on their own if something breaks
The downside is that if some piece of firmware or hardware has a vulnerability you have a larger attack surface.
But that's still a lot easier than managing laptops, which are unwieldily in a DC for a lot of other reasons.
Since I've been looking at this situation from a resource point of view for a bit I see obvious savings in slowing down certain accepted processes. For example, an entity that continuously updates needs to be continuously scraped while an entity that publishes once a day needs to be hit once a day.
