That put Wifi and bluetooth in their iPads was important, too but I wouldn't call that an innovation either.I wasn't aware that you got to decide what was groundbreaking or not. For me touch ID is just as important as anything you mentioned there. I couldn't care less if it's considered groundbreaking or not.
Touch ID was nothing new and didn't change the way people use their devices.
At least the mouse and multi-touch certainly did.
