It’s a modern consumer gadget phenomenon. A company such as Apple will announce an updated version of last year’s product, and people rush out to buy the new model — while their perfectly functioning old product is still just fine. Why?
I’ve thought about this before, but it’s on my mind today because of a discussion related to Wednesday’s story about iPads in schools. A commenter brought up the question of why people today seem to feel the need for the latest of everything. Why is it that a 10-year-old car is unacceptable to some people, even if it still runs perfectly and has no other problems? Why is furniture that’s perfectly functional tossed out for something new? And why was that iPhone 4 from last year replaced in October with an iPhone 4S?
I suppose you can explain a lot of this by calling it an appeal to fashion — in consumer societies that are fabulously wealthy by any standard the world has known before. By historical standards, we have excess wealth in our pockets, excess time on our hands and excess choices to spend them on. I haven’t studied consumer psychology on this, but I have a theory about what causes people to replace things so quickly. Let me run it by you and you tell me what you think.
