I always hear of people buying a new one every year or every other year and I never understood why. I don't think much changes on phones that quickly but I could be wrong. I think people feel obligated more so to have the latest new and shiny thing. Since most phones these days are not cheap, it makes more sense to spend more on one built to last and use it for 4 or 5 years because you get a new one. What are your thoughts on this? How often do you think people should be buying new phones if their old one still works perfectly fine?
