John Gruber and Serenity Caldwell were talking about this on their podcast, arguing that 3D Touch and long press should be combined. I actually agree. What I love most about 3D Touch is the haptic feedback. I would like to see haptics in many more places throughout the OS. One other thing that came up regarding 3D Touch was discoverability. But couldn't the same thing be said about long press. Go to the mail app on the iPhone and click the icon to create a new email. There is no icon or anything that indicates how to attach a document or photo or any formatting options. Those do exist on the iPad Pro keyboard but when using an iPhone you have to long press to get those options. Same for copy/paste. I just don't see what makes 3D Touch less intuitive than long press. In fact I prefer 3D Touch because of the haptic feedback. I'd like to see the two combined. For example when you 3D Touch on an icon it could give you the options to remove or move the app. I think once people use it more frequently it will become second nature, just like right-click is in the Windows world. Yes things should always be as intuitive as possible but at the same time making something easy for grandma to use shouldn't preclude adding useful features. People might have to learn something new but as long as it's not difficult and isn't hard to remember I don't see what the problem is. If Apple removed 3D Touch and haptics from the iPhone I'd be a very sad customer.
