     I needed to buy a digital camera, one that was simply good at taking good snaps (快照), maybe

occasionally for magazines. Being the cautious type, I fancied a reliable brand. So I went on the net,

spent 15 minutes reading product reviews on good websites, wrote down the names of three top

recommendations and headed for my nearest big friendly 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 an

assistant, "Can I have one of those?" He looked perturbed (不安). "Do you want to try it first?" he

said. It didn't quite sound like a question. "Do I need to?" I replied, "There is nothing wrong with it?"

This made him look a bit insulted and I started to feel bad. "No, no. But you should try it," he said

encouragingly. "Compare it with the others."

     I looked across at the others: shelves of similar cameras placed along the wall, offering a wide

range of slightly different prices and discounts, with each company selling a range of models based

around the same basic box. With so many models to choose from, it seemed that I would have to

spend hours weighing X against Y, always trying to take Z and possibly H into account 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 by making the right choice,

the clever choice, the wise choice. In the end, I agreed to try the model I had chosen. The assistant

seemed a sincere man. So I let him take out of my chosen camera from cupboard, show how it took

excellent pictures of my fellow shoppers… and when he started to introduce the special features, I

interrupted to ask whether I needed to buy a carry-case and a memory card as well.

     Why do we think that new options (选择) still offer us anything new? Perhaps it is because they

offer an opportunity to avoid facing the fact that our real choices in this culture are far more limited

than we would like to imagine.
