answer:Like all decisions about which device to get, it all depends on your needs and expected use. What in particular has been rumored to be featured in the S5 that makes you feel you should wait? And what would that have over the pure Android experience of the Nexus 5 or the cool features of the Motorola X? And more importantly, while Android is significantly more powerful (in terms of functionality) than iOS devices, if this is your first phone, you may not have any need or desire for any of that functionality. The iPhone might be a better choice. Maybe you could provide some details on what you are looking to do with the phone, what carrier you are tied to (if any), and what are important features.
