A lot of people aren't understanding to full future potential of USB 3.1 and above. Up until now USB has only been used for data transfer, whether it was the data from a webcam, mouse or keyboard or some other low powered device as well as supplying small amounts of power to devices such as passive external HDDs or Pendrives.
USB 3.1 will change all that... Why? Because as of now so many things you connect need a separate cable to a mains supply. Your monitors, active speakers, amps, etc... Now you just need the one cable to not only supply the data but also the power that makes it work and best of all, these new devices will all use the same connectors which won't matter which way round you try to insert it. USB 3.1 hubs will now act just the same as a multi plug adapter, which ultimately means far less cables everywhere... although you will have to factor this in to your PSU requirements... after all, USB can only supply up to the maximum of what your PSU is pushing through...
