Techological devices,a neccesary part of our daily life ,are increasingly popular due to diverse function available to people.Continuously updating technologies has brought tremendous benefits to us ,especially improving the standard of living.There is much conjecture over whether we are more enjoyable to purchase it when a company launches a new product or to wait until it is prevalent among most people.I believe we should choose a reasonable way of consumption .    It's undenial to say that the new technological device can make our life or work more convenient and efficient.But in fact many young people just persuit fashion rather than consider its pratical use.They often want to make a show among their friends because their immature consumption view has an incorrect influence on their consumption way.For example,computers help young people in various ways.However,with the fast speed of the latest product they usually play computer games instead of aquiring information and studying online.Chatting on the Internet is another way to kill their precious time.Worst of all ,investigations have indicated that more than half of time that young people spent online was exhausted on browsing porn movies,pulp fictions or erotic photos and so on.I think when pkarents decide to buy a new technological device ,they should consider whether their children can make good use of its advanced function.    On the other hand,as we all know that electronic products have a rapid updating speed.It's too expensive to buy them  when they first hit the market.Under this situation,many people make a chioce to wait until price starts to decrease.For example,iphone5 was offered in the mareket,the price of iphone4s had fallen 30%.The same will happen to iphone6.If you can't afford it now ,you'd better keep enough patience for waiting.The same is true with other technological devices.    Admittedly,buying a new product enables us to gain fresh experience.However,we should take many factors into account such as our economic ability and its practicality.Therefore I still hold my opinion that we shouldn't follow a new device blindly.
