Rumor has it that the iPhone 6S will incorporate Force Touch (among possibly RAM and CPU upgrades). I understand that the iWatch currently sports this feature, but in what manner does it use it? Is it accurate and actually a viable means of usage? What exactly does this mean for iPhone and apps that would like to support it? What, if any, hardware upgrades are needed to incorporate this into the 6S? Is it something that could halt production of the phones and be delayed for IP7? Any good examples of where force touch would shine on the iPhone? Just wondering if this is a complete game changer for Apple.
