It was obvious that samsung tried to make their devices look and feel like apple devices. what isn't obvious is why apple should have exclusive ownership over things making a stretching gesture with your fingers to make something bigger. not only were they not the first to implement it, it is entirely a natural movement and is not something that should be anybody's property.
That's irrelevant, because apple didn't invent the gesture. Microsoft's surface table, minority report... Every time we've seen multi touch screens, we've seen pinch to zoom. When I bought my grandma an android tablet, pinching to zoom was the just about the only thing she didn't need instruction on. She didn't understand that tapping the word 'Internet' opened the internet, but she understood that stretching something made it bigger.
