How did cell phones have a bad affect on society?

Cell phones are integral to modern societies because of their usefulness in transmitting the information upon which post Industrialized societies depend. However, this technological leap forward is not without repercussions. Teachers are having increasing difficultly maintaining their student's focus in class. This is due in part by the increase in both cell phone ownership amongst younger individuals as well as the increasing sophistication of the devices they own. Safe to say, one could easily understand why a young adult, bored in his or her last class of the day would rather turn to tetris than spend another hour repeatedly solving Linear inequalities or texting their friends instead of reading Oedipus Rex. Tweeting could bring about a radical shift towards Narcissism but that's an opinion of mine not a fact. There are other consequences and others are sure to arise in time but a problem developed nations are dealing with today is the issue of teens ignoring their studies during school to play with cell phones.
