Mobile phones can cause phantom sensation. A recent study has shown that people are feeling their cell to be an integral part of their personality. If they are not carrying a phone, still they can feel the presense of the phone. The use of cell phone is almost approaching the levels of Addiction in people using it. More ever recent studies have shown that cell phones are harmful to the hearing capability of a Human Being esp. children. Also this growing addiction problem is only going to accentuate in the future with call rates dropping due to competition with internet phone and also internet phone plans availoable in countries like the US.
I suggest people should use mobile technology to leverage their relationships and business and should not become slaves to technology.
