I've had the galaxy s4 for a day short of two weeks. I have to either return the galaxy today or keep it and sell the iphone 5. Has anyone else been faced with this decision? I just can't decide. I know it's all about personal preference, and what works best for me, but they both work great for me in different ways. Anyone have any outweighing factors that kept them going one way or the other on this particular decision?
