They copied Apple on so many other things that the only thing left to copy was the pricing.
Samsung is trying to be Pepsi to Apples Coke. In many ways the S6 is a much better device than the iPhone 6 at around the same price points. They're going to lose some sales with the removal of the swappable battery and SD card slot but they should be able to bring on new customers with a better design and better materials (like me). I don't like paying large premiums for more inbuilt storage, but I prefer inbuilt memory to external where you can't install apps. Things like wireless charging, fast charging, Samsung pay, super high res screen and 3gb or ram are compelling. My only worries are how the battery life is, if the processor can keep up with the res well and how cool the device runs under load. If they can nail all three of those, I'm on board.
