A lot of times, we buy things that we don't really need. This is true, especially in the case of consumer electronics. Plenty of things like laptops, computers, tablets, and smartphones are always bought for the simple fact that they are new. Other times, people just buy them to be "in" and be cool. They want to brag that they have the latest mp3 players with the biggest memories, or the latest phones with the coolest looking games.
