I felt almost the exact opposite, in that I think the concept was great but the execution fell a little bit short, mostly in build quality/button-feel.

The biggest single win for me is replacing the right stick for camera control, as the trackball emulation with haptics on the touchpad is so much faster and more responsive than a traditional thumbstick. There are some games that I'd still prefer the standard twin sticks or dpad (twin-stick shooters maybe, some platformers, or hyper-specific designed games like Brothers: A Tale of Two Sons), but overall I've much preferred the touchpad over thumbsticks for almost every first- or third-person game I've played.
