The demand for portable electronic consumer products is rapidly increasing. Examples of fast-growing markets of portable products are notebook computers, cellular and cordless phones and camcorders. Figure 1.1 shows the expected worldwide shipment of cellular handsets until the year 2004 [1], with the total number of handsets sold increasing dramatically. At present, almost half of the shipments of cellular handsets are replacement sales, which means that people who already have a cellular phone buy them. By 2004, almost all cellular handsets sold will be replacement sales.
