I needed to buy a camera, one that was simply good at taking good snaps (快照). So I went on the net, spent 15 minutes reading product reviews on good websites, wrote down the names of three top recommendations (推荐) and headed for my nearest big camera store. There in the cupboard was one of the cameras on my list. And it was on special offer. Oh joy. I pointed at it and asked a salesgirl, “Can I have one of those?” “Do you want to try it first?" she said. It didn’t quite sound like a question. “Do I need to?” I replied. “There’s nothing wrong with it?” “No, no. But you should try it,” she said encouragingly. “Compare it with the others.”

I looked across at the others: shelves of similar cameras placed along the wall, offering different prices. With so many models to choose from, it seemed that I would have to spend hours weighing X against Y, always trying to consider Z and possibly H at the same time. But when I had finished, I would still have only the same two certainties that I had entered the store with: first, soon after I carried my new camera out of the shop, it would be worth half what I paid for it; and second, my wonderful camera would very quickly be replaced by a new model.

But something in the human soul whispers that you can beat these traps (陷阱) by making the right choice. In the end, I agreed to try the model I had chosen. The salesgirl seemed a kind girl. So I let her take out my chosen camera from the cupboard, show how it took excellent pictures of my fellow shoppers... and when she started to introduce the special features, I cut in to ask whether I needed to buy a carry-case and a memory card as well.

Why do we think that new choices still offer us anything new? Perhaps it is because they offer a chance to avoid facing the fact that our real choices in this culture are far more limited than we would like to imagine.
