It comes on the heels of a few different iPhone 8 rumors spinning around the Internet, including one that the company would launch three new iPhones this year. Among others we've already heard before: the curved screen, an alternative interface to the Home button, eye- and face-scanning technology, and even wireless charging (though maybe that's out of the picture given today's report).
Time will tell. There are some real advantages to the USB-C standard. It can transfer files faster than any other connector in its class. It can be used bi-directionally, meaning -- at least theoretically -- you could charge something else in a pinch with your iPhone. And it's now used in the latest Apple MacBook charger, so you could potentially use the cable for that, too.
