In order to make a decision about what kind of connection I should use, I did a little informal research and asked 10 of my friends about their internet connection. Five of them used DSL phone lines and five of them used the new Road Runner cable connection. After talking with them, I looked at the following variables: 1) how much they spent on their internet connection each month,
2) what they spend the most time doing, surfing the web, downloading music or downloading data,
