In my opinion, the smartphone is one of the most revolutionary creations of this century. Actually, it is no exaggeration to say that human life has completely changed since the smartphone was devised for some of the reasons. The first reason is how it changed the way we consume information and communicate. The way we consume information has changed from talking to each other to reading newspapers to watching TV, to gathering information on the web using a computer and now a smartphone. Same is true for communication. Our smartphone offers us several forms os communication: calls, text messaging, email, blogs, etc. That is extremely convenient as we can get any information whenever we want and wherever we are. The second one is how smartphone changed the way we behave. The first thing we do in the early morning is reaching for our smartphone to turn off the alarm clock. As the day goes by, we use our smartphone in the way to work, during meal times, at work, on the way home, even in the bathroom and in bed. Sometimes it really makes us more productive and efficient, sometimes it's such a hindrance to our work and communication. The third one is how it changed the way we use technology. Our society tends to ise devices that make our lives easier and more convenient. Taking this fact into account the mobile industry developed one device that made several others obsolete. Sales dropped for landline phones, desktop computers, digital cameras, mp3 players, gps devices,etc. Not too long ago there was a time when you needed to carry all those devices with you. In conclusion, in the advancing age of information technology, the mobile phones have become the essential part of life and its popularity cannot be denied; now the cell phones are not luxury but the necessity.
