The touchpads are indeed slightly larger at 34.5mm versus the Deck’s 32.5mm. The whole grip angle and triangle of buttons-sticks-pads is rotated from the Steam Deck slightly because your hands will be closer together, so the angle from your shoulders changes. One review mentioned that they wished Valve had actually gone a bit more extreme with the angle, but that didn’t seem to be a common opinion.
