How do you choose between the iPhone 5 and Galaxy S4? On the one hand, the iPhone 5 is an entirely known entity that just works. You might not be getting the most exciting or feature-rich smartphone, but at least you know exactly what you're getting. Samsung's Galaxy S4, on the other hand, is world's apart from the iPhone 5: It's huge, and massively powerful, and it has a ton of features that might be awesome or gimmicky, depending on your point of view.
