Using a NUC with peripherals to replace a laptop sounds inconvenient to me. Each time you arrive at the customer's place you have to unpack and connect all peripherals, do your work, and then disconnect and pack up before you go. You'll see that the employees will forget one or the other item (e.g. mouse) and are inconvenienced when they arrive at their next customer. The benefit of a laptop or tablet is that it is all-in-one, without separate peripherals. I consider a NUC only beneficial for two use cases: either to replace a desktop computer, or as a headless server, where no human interface is required.
