Keeping up with the Jones' is an expensive pass time. Be it flag ship phones, or fancy cars, or pools, mansions, overseas holidays, gaming PC parts etc. etc. It's all showing off. There's little actual NEED to have the latest flag ship other than being able to say you have the latest flag ship. The question is, can you put up with the shame of not having the latest phone every year? I usually just skip every second model, so my S7 edge will be getting replaced this time around. My vice is fast cars, so I can bare the shame of having an old phone.
