Mobile phones, the Internet and wireless e-mail devices have taken a tighter hold on an increasing number of users. Meanwhile, television is slowly but steadily declining as a media form people can't give up, from 47 percent in 2002 to 43 percent in 2007, according to Pew.

Landline phones, which 63 percent of people said would be the most difficult to give up in 2002, dropped to only 40 percent in 2007. This dramatic decrease, coupled with the rise of mobile phones, points to the fact that mobiles are overtaking the landline phone market. Many people are opting to have only one phone, and choosing mobiles over landlines.
