Sometimes your work computer is so locked down that some work tasks are made much easier by having a machine you have full access to. For example we needed to program an Arduino-type board, but that's not possible with our work laptops (no admin rights, USB ports disabled, etc); we never found a solution other than a personal laptop. Or a colleague needed to run a supplier's simulation tool that needed admin rights, and couldn't get an exception fast enough. Or you need to run a Linux tool.
