Is Samsung Galaxy S4 worth the hype?

Samsung has just launched its flagship device the Galaxy S4. So how does the smartphone stack up against its main competitors, currently the Xperia Z and the HTC One? In terms of design, Samsung hasn’t done anything new and its an all plastic body which is disappointing and doesn’t match up to HTC One’s aluminium finish. The S4 however does appear to have a faster processor and a stunning screen.
