People in contemporary world can hardly imagine their lives without machines. Every day either a new gadget is invented or an old one is improved. Different people appreciate new inventions differently. Some suppose that sophisticated gadgets are really useful and necessary, while others find them absolutely awful as they influence people badly. As for me, I am pretty sure that gadgets make people`s lives easier.

Firstly, they do all kinds of dirty and hard work, as cleaning. Secondly, devices can save a lot of time as well as storage space. For instance, a computer disk can contain the same amount of information as several thick books.So, machines help people in different spheres.

However, opponents of this point of view are definitely sure that gadgets affect people negatively. People are reluctant to work due to the influence of machines. People become lazy and disorganized. They just expect their latest gadgets to do everything instead of them. Moreover, according to scientists, a great number of widespread devices produce radiation that can cause serious health problems. Furthermore, more and more people are becoming addicted to their modern gadgets, for instance computers, TVs or mobile phones. So, they neglect their home obligations, work or school and spend all their spare time in front of a laptop screen or a TV-set.

In conclusion, I firmly believe that in spite of all drawbacks, gadgets have, their benefits are much more considerable, as they save people`s time and let them enjoy life.
