Actually, the more I think about it, the more offended I am by the very nature of this post.
Your basic premise is that nothing is different because everything is copied, so the only way to exist is to continue to make new things for others to copy. I'm sorry, that's just not acceptable. It's not good for business, it's not good for "innovation", it's not good for consumers.
Sure, Samsung might make some phones that are cheaper than iPhones (although they often do not do so) and that is good for consumers in the sort term. But if folks like Apple lose their incentive to bring out new features (because they just get copied, anyway), then what you get is differentiation based on price. This is where the PC market is today - all the PCs are essentially the same, and your average consumer buys strictly on price. There's no margin for real R&D, and the products themselves are cheaply made. In the long run, the consumer is harmed by having nothing but a sea of vanilla (or imitation vanilla) to choose from, harmed because no one has any money to invent really new things.
In Apple's case specifically, they are a hardware manufacturer that uses software to differentiate their products. They make their money on the hardware and give the software for those devices away. Mountain Lion is $20, and that covers all the computers you own. iOS upgrades are completely free. When someone like Google/Samsung copies the "cool stuff" from Apple's labs, then that differentiation disappears, and Apple ends up being compelled to chase their products down the rathole of price, along with everyone else.
Aside from all that, it is simply wrong, IMHO, to allow and support blatant copying. It's not right that Milo T. Farnsworth never made any real money from inventing TV. Just wrong. The fact that Apple (or any other corporation) is not an individual doesn't change that. True innovators deserve our respect and support.
There are plenty of ways to make a smart phone that don't have the same UI as an iPhone. I personally am proud of Palm and Microsoft for inventing totally different paradigms. They both did things that are very interest. THAT is innovation. THAT leads to better products. THAT is what the world and consumers need.
Copying someone else and putting some lipstick on it is NOT innovation, it's criminal.
