Not such a long time ago, say five to six years, people were still using wide and heavy cell phones. They were only able to do one thing : to give a phone call. Nowadays, the technology enabled smart phones : they are able to browse the web, to be your personal assistant, you play games with them, and you even record movies or take photos that could be instantly uploaded on Facebook or Tweeter. What a revolution !
