So I was thinking... instead of "3D touching" pressing on your screen a little harder, how about just hold? On the home screen this obviously enable's app deletion. But this could easily be removed all together and be added as one of the options when you tap and hold an app. Also with regards to photo's and previews in applications, just tap and hold to preview then tap and hold again to go in? Did you really need to rebuilt display technology for something that could be built into the software itself... Am I missing something here?
