By now most people are familiar with P2P and have been using it extensively. But most people don't use it to its full capacity. With Limewire pro you can download loads of songs but not videos. You need to get Bitorrent which can download videos and games, but not songs. All of this is assuming you have dsl. Another great internet tool is Skype were you can make free calls to other skype users and make cheap calls to land lines and cell phones.
