The S4's evolutionary design may seem a tad plain and boring, but we have to hand it to Samsung for managing to squeeze in a larger display in the same chassis as the SIII. This meant shaving down the bezel even further, which was quite thin to begin with, while keeping the height and width pretty much same. In fact, the S4 has gotten slimmer and a tad lighter as well. The low weight can be attributed towards a strict diet of plastic/poly-carbonate for the entire chassis. On one hand, this seems like yet another let-down , but you do get the optoin to remove the battery.
