Will you need to connect your new Chromebook’s micro HDMI port to a customer’s old VGA monitor or projector ? Ever been at a location with flaky Wi-Fi but a working wired network so you need a USB3.0 to Ethernet adaptor and an RJ-45 patch cable ? Do you travel to many customers and need a range of adaptors to suit ? Do you need a spare power supply or two to allow you to work at different locations without lugging a lot of weight around ? Do you need a power supply to work off 12V in a car plane or boat ?
