Another domino has fallen in the march toward a post-headphone jack world. Today Google became the latest company to drop the once ubiquitous port from its phones, though it hardly devoted any time to its own courageous move. The driving motivation for dropping the jack is pretty clear after a quick survey of the mobile landscape: the Pixel is moving to an edge-to-edge display.

“The primary reason [for dropping the jack] is establishing a mechanical design path for the future,” Google product chief Mario Queiroz told TechCrunch after the event. “We want the display to go closer and closer to the edge. Our team said, ‘if we’re going to make the shift, let’s make it sooner, rather than later.’ Last year may have been too early. Now there are more phones on the market.”
