pinch-and-zoom is a good idea. But it is just that: An idea.
Its invention cost no money and society as a whole is not served by granted exclusive monopoly over it to any entity.
The entire discussion is turning to be absurd. Is pinch-and-zoom (and friends) all that separates Apple from the competition?
In other industry manufacturers learn from each other (seatbelts, suspensions systems, transmissions, etc), but somehow when it comes to software and electronic devices we want to stop progress and grant monopolies to every oh-so-little idea.
In so far as this is true -- that Android devices' pinch-and-zoom doesn't behave at all the same as iPads', and that this makes them much worse to use -- those Android devices have not copied what Apple did.
(I have no opinion about how much Samsung actually copied from Apple or whether what they did was legal; I haven't looked carefully enough at the case. I'm not passing comment on that. Just saying that you can't reasonably say both (1) that what Apple have rights over is a very refined implementation of pinch-and-zoom that differs from anything you'll see on an Android device, and (2) that a maker of Android devices copied it. At least, not without a further explanation of how they screwed it up so badly.)
