Why? USB-C is better than Lightning, letting you connect Apple products to more devices. It's the new standard for charging Android phones and many laptops, including Apple's own. In Apple's insular world, where Cupertino engineers mostly don't have to trouble themselves about the existence of Windows laptops and Android smartphones, USB-C solves real problems.

Our world has too many incompatible cables and dongles to bridge the gap between old and new devices. USB-C offers a path to a simpler, saner future.
