All signs, including what appears to be a substantial leak to a Chinese blog, point to the S 4 being made of plastic, just like its predecessors in the Galaxy S line. This rankles us gadget bloggers, because we hate the plastic. We praise the aluminum cases on the iPhone 5 and HTC One. We marvel at the thick, lovely-feeling polycarbonate on the Nokia Lumia 900 (yes, polycarbonate is a plastic. But it's a better plastic.). We call the Galaxy S line cheap, and light, and plasticky, and we say it feels less than good in the hand. And Samsung sells about a billion of them anyway, because who cares what we think? Nobody. The new Galaxy S 4 will be made of plastic. White plastic and black plastic, probably.
