I was just thinking...USB ports - those rectangular things we all take for granted - have allowed us to do so much. Previously, when you had dedicated ports for everything, connecting your devices was a little bit different. c: Now you just plug and play everything - WiFi radios, Bluetooth radios, TV tuners, speakers, controllers, keyboards, mice, printers, scanners, fax machines, storage devices, cameras, and so on. Some will even carry an extra display or Ethernet. ^u^
I guess that's why they call it universal. :3
