Hard to be inspired by Apple if you already did it before yourself. Not like Apple ever invented anything. They took existing ideas and made it sleeker,more expensive and nice marketing. iPhone wasn't a thing until 2007 and Smartphones been on the market since 1994. LG Prada in 2006 looked basically the foundation for how Smartphones look today. Also was the first with capacitive touchscreen. Maybe Cerny said it I dunno but Sony was using the feature on both PSP and Vita before PS4.
