Personally, I hate when people use the term iPhone killer or S4 killer. First, whenever somebody throws out that term, the unit never lives up to that. Second the objective of any company shouldn't be to kill your competition, but to compete on a fair and level playing field. Competition is good for everyone from the consumer to the OEM. The consumer wins because competition leads to more choice and lower prices. For the OEM, it provides an incentive for innovation. Finally, each OEM provides a separate and unique experience on their devices. As much as I hate Apple, they offer a unique experience. Samsung has provided a unique experience to Android with the S4. The Moto X will provide a unique Android experience over the S4. The real question is how well will the Moto X compete in the market? That has yet to be determined.
