Here’s a prediction: One day your smartphone will be an unbreakable sheet of solid glass with no sockets, jacks or visible moving parts.
That’s always been Apple’s ambition. “For more than a decade, our intention has been to create an iPhone that’s all display,” said Apple Chief Design Officer Jony Ive at the iPhone X launch last year. “A physical object that disappears into the experience.”
That certainly sounds good, especially if you care about smartphone design. But the problem with phones is that you need to interact with them, and that means some elements have to be included on the front of the device.
