BeagleBone Black has just one USB port, which is often very inconvenient. For example, if you want to run Octoprint accessible via WiFi and control a 3d printer, two USB ports will be needed. Certainly, a USB hub is an option, but it makes the setup more brittle (some USB WiFi dongles won't work over some hubs) and more expensive.
