I like to joke that the only thing more personal than a persons cell phone is his underwear. Mobile phones are not shared, like traditional phones or desktop computers might be, so they are a uniquely targeted means of communication. The
mobile phone is the most personal piece of technology that most of us will ever own.
• Our mobile phones are with us all the time. They know who we call and who we text, and they can triangulate where we are throughout the day.
• Smart phones have access to our entire address book and calendar. They can see what websites we are looking at and what applications we are downloading.
• Our mobile phones know what kind of entertainment we like. We use them to download and play videos, play games, or listen to music.
• Mobile phones can even hold and distribute digital likenesses of us with cameras, videos, and voice recordings.
