Tastes have been changing. We change with the changes in our demographics and psychographics. We keep demanding goods with higher and higher value as or careers progress and our aspirations, disposable incomes and status grow. For many years refrigerators and washing machines were available only in one color-white. No longer. For many years telephones were available only in one color-black. No longer. For many years only men smoked and women wore earrings. No longer. Now women cut their hair short and men sport ponytails and wear earrings.
Not only this, there are several changes technology has brought. Today you need not be strikingly rich, but you will still need the feel for a mobile phone, a fax, a PC etc .if you value time and believe that technology can improve your quality of life.
