Seems like you'd still need the 350ms delay (or some amount of delay) for pinch-to-zoom because the two fingers don't touch the screen simultaneously. The sensor reads the first finger's touch and the software has to wait to see if a second finger touch comes in before it decides if the first touch is a tap or the start of a pinch.
