The China-bound Sony Xperia C could be the right opportunity to smuggle some big-screened, quad-core goodness into markets where those things usually fetch a high price. It's certainly the right size too. Five-inchers don't necessarily have to come with high-end price tags. There's demand for affordable options too, which the Xperia C isn't the first to address. Sony has obviously been watching the Samsung Galaxy Grand, while HTC and LG aren't indifferent either.
