Apple Is Innovating Their Home Buttons September 22 2016
Apple introduced a revolutionary new solid state home button with the iPhone 7 and iPhone Plus. They use haptic feedback to simulate the press of a button; you're not actually pressing a button. Over the past few years, Apple has been moving away from any type of moving parts, from getting rid of the optical drive to implementing solid state hard drives in all of their computers. It will be interesting to see what Apple does next!
