I really love the Taptic Engine in all of the facets it's used on the 7, even the home button. One weird thing though is the feedback of pressing the home button while the phone is laying on the table. The haptic feedback all but disappears, and you're left to look at the screen to see if your press worked. It seems as though the back of the phone is primarily responsible for the feedback of the home button, and you need to be holding the phone to feel it. On the table it just disappears backward into the surface.
