I for one actually prefer the corkscrew zoom over pinch zoom, in lets say the browser.

But I do understand some apps need gestures (press, long press, swipe in 4 directions, screw-clockwise, screw-anticlockwise) that you run out of good options and need to stick with pinch-zooming. I do say multifinger-swiping (on a handheld) is not as user friendly as they make it out to be, but this may be a whole another thing on tablets.
