The Samsung Z3 with Tizen is state of the art. Love it because it lacks gimmicks like Touch ID, Siri, 3D Touch, Apple Pay. Koreans really know design better than Westerners. Got to give credit where it's due.
Touch ID is in no way a gimmic. It is an invaluable addition to a smartphone. I will never own a phone or tablet without it again. Also, if Koreans really knew design better than westerners why do they constantly copy design? It's not just Samsung. Korean car companies absolutely mimic Japanese car design. They make great cars but they are hardly original in their design.
