I know what you're thinking: Ugh, another new connector. Right now, yes. To take advantage of USB Type-C, currently you'll need an adapter. But once peripheral makers start producing devices with USB Type-C ports, you'll be able to buy, say, a monitor with a single, convenient cable that plugs into your laptop and provides both power and a video signal. If that monitor happens to have speakers or an integrated camera, those will be able to work over the same cable, too.
