Every year, we spend a higher and higher portion of our incomes on electronics. Items that just a few years ago seemed like something from a futuristic space age are now considered absolutely essential to modern life: MP3 players, smart phones with Internet access, laptop computers, external hard drives, digital cameras and so much more. But unless you want to completely withdraw from society, it is almost impossible to avoid these electronics. What's more, even if you invest in a few of the now-"essential" devices, constant upgrades in technology and "generations" mean that you almost never get a break from the increasing total cost to own these devices.
Just when you think you have the latest and greatest version of the smart phone, another one comes out on the market with newer, better features, trumping its competitors and rendering previous generations appear outdated within a few months. This is why one must know how to sell a phone, not for a business point of view, but for a personal point of view. You can always sell your current phone or other gadgets to be able to qualify for an upgrade. This way, you are recycling phones, which is friendly to the environment, and you are also saving yourself money!
