3d touch does take some getting used to. Surprisingly, it's the light setting that helped me with separating a peek from the jiggle mode. When more developers update their apps for 3d touch, I think people will find it worthwhile as long as there's some uniformity between apps so that you know what to expect, the way we know what will happen with a right click on the PC. If it's inconsistent like Apple Watch's force touch, things will be bad.
