IMO there is a fundamental difference between pinch-to-zoom and slide-to-unlock. The pinch gesture -) has quite a bit of prior art, most notably minority report -) is similarly self-evident on a multi touch surface as drag-and-drop using a mouse or modifier keys on a keyboard Meanwhile slide-to-unlock is a simulation of a real world object on a multi touch surface. I'd also argue that it's an idea Apple has clearly introduced with the iPhone with not much prior art. Conclusion: Those gestures should be analyzed separately when one has to decide whether a design is infringing or not.
