These are convenient beliefs for anyone justifying some e-commerce share prices, but they are already mostly wrong. The reasons should surprise no one. The Internet is not a dominant technology but rather a network of people. It is a rich and highly flexible means of communicating that is rapidly achieving pervasiveness because more and more people find it easy and convenient to use. But it is those people's preferences that will count; and for most people, shopping is more than just a means to an end. Even if the Internet provided a perfectly efficient way to shop it would not provide a satisfactory alternative to the physical enjoyment of sniffing a ripe melon, say, or trying on a cashmere sweater.
Of course, some products, such as music and banking, can be distributed electronically with success and cost saving. But most purchases cannot be reduced to digital code. And distributing physical goods is cumbersome (笨重的) and expensive. Behind even the most exciting user interface there are old-fashioned warehouses and lorries, customers who decline to sit at home waiting for purchases to arrive, and goods that must be re-wrapped and expensively returned. No wonder that the cost of getting goods to customers' homes so often soaks up the notional price advantages of e-commerce.
What Internet shoppers have quickly realized is that the web is an addition to, and not a substitute for, their shopping habits. It is wonderful for gathering up-to-date information about products and prices. Cyber Dialogue, a research firm, estimates that in 1998 23m Americans sought information online, but then made their purchases offline, compared with only 17.7m who did the whole thing online.
