Today, a variety of technologies in our lives prominent place . No modern man can never imagine my life without gadgets. And we all are dependent on electronic technology . without many as it seems to some people , life is simply not possible today .In this essay, I have presented several pieces of modern technology, of which I had to choose only just one. Computer, mobile phone and fridge is basic inventions that take place in our lives . And choose one thing was very difficult , but I decided for myself that in my life the major inventions of this phone .The latest mobile phones are sophisticated computers, but on a microscopic scale. How many computers and devices placed in this little box ! Amazing!The main purpose of the phone is of course connected with others , the ability to communicate at a distance , but the latest phones have many other different functions. For example: sending SMS text messages , listening to music , access the Internet and social networks , the ability to call up using Skype and see companion , playing computer games , camera, video , photo editing , recording on the recorder , the ability to read e-books , use the built-in flashlight , calculator , calendar , display date, time , weather, maps of the world , as well as much more!Modern phone can replace a variety of devices , and so I think that the phone is one of the most important inventions of mankind !

I think that this statement is very incorrect and I do not agree with you. People need libraries and will always need libraries. Not everyone has access to electronics and can read books on them. Besides, most books online aren't free but libraries are free and anyone can read books from libraries. Personally, I like reading physical books because I love the smell when you open up a new book and put your face in it, the smell is amazing. You can't do that with electronic books. This is why we need libraries and real books instead of books on the internet.
