Owning an iPhone doesn't mean to be an investment accounting to me. This had turned to be status symbol, even the person who doesn't have proper shelter holds an iPhone. This is the reality happening around the world, mainly in the third world countries. The market movement is directly connected with the economy too. An investment should appreciate in value whereas an iPhone keeps depreciating.
Most people that makes use of iPhone don't even use it for anything that can generate money for them. I don't have problem with people using iPhone but if an iPhone can't in anyway generate money for it users it is a complete liability. The worse thing about people using an iPhone is that they don't really know the function of the phone, it is only used for formality. The reason why I think IPhone is a waste of money is because it does not add value to it users instead it reduce it value. Everything about the device is expensive, maintenance and repairs of components of the device.
