Apple has announced its newest line of MacBook Pro notebooks, and true to the leaks, it comes with an OLED strip instead of function keys. As the company's Phil Schiller notes, function keys are a decades-old technology that shouldn't really have a place in a laptop from 2016. In its place, the company is adding a retina display touchscreen (with multitouch) that it's calling the Touch Bar. As well as contextual menus that change depending on what app you're in, the power button on the far right now doubles as a TouchID sensor.
