I don't understand people who think this lawsuit is unjustified.
Apple is not stifling competition, it's forcing it. Saying there is no other way to design a phone shows lack of imagination. What people are really saying is there is no other way to design an iPhone and they've already accepted iPhones as the way it should be.
Why is that a bad thing? If that's what people like and it is accepted as the way it should be, why would your pursue something else? It's like saying that you should innovate for the sake of innovating. That makes no sense, especially as a business. Some designs just got it right, and perhaps the iPhones form factor was one of them.
Both companies had device designs before the iPhone launch that had similar form factor -- touch screen, rectangular, buttons. If the trend is that people like silver bezels and a single button, why is that suddenly stealing? Tons of products follow design trends for finishes and materials.
Think about TVs. If everyone wants flat screen with a thin gloss black bezel and inputs on the bottom, and that's what everyone is used to, what am I supposed to do as a manufacturer other than give people what they want? Both those design cues have existed in some form or another. I think a lot of people would be unable to differentiate one generic TV from another.
I think we can agree that a smartphone right now has to feel good to hold and screens should be rectangular. The general form is thus predetermined by these things, leaving you to designing the case and software. The Samsung device has a different shaped button, says Samsung right on it, has a different operating system (though something people are still used to,) and completely different hardware.
People happened to like the minimalist Apple design, so why not just go that route? The internal electronics, implementations, and software is entirely different, thus I really don't see it as a big deal.
Just my two cents. Perhaps it doesn't hold up legally, but then again, laws are often written by professional politicians who have no experience in anything remotely practical or grounded in logic.
