"Cheap plastic" is not a meme. People have compared build quality as long as manufactured goods have existed. Many people associate heavy with valuable because traditionally, making things out of metal cost more and increases durability. Maybe the use of composites will change this perception. Does using a glass display instead of a plastic display increase the chance that the display breaks? Yes. Does it increase weight? Yes. But glass is more scratch resistant and has a better feel to it, so most people think it's a worthwhile tradeoff (Samsung seems to agree).
