I'm old enough to remember the world before cell phones. Even today I don't have one, don't need one, and don't have any thoughts about getting one. Before cell phones, people drove much better; you didn't see people failing to go when the light turns green, or people swerving outside of their lanes while jabbering and driving. You didn't see people in stores talking loud behind you, and you didn't see people in public places putzing with smart phones. Yep, I can definitely imagine that. If it were legal to carry a cell phone blocker in restaurants and grocery stores, I'd be among the first to carry one.
Now a days many of the people using cellphones, 1 person having 2-3 cell phones and 8-10 different sim cards. The prices of Cellphones are very cheap in the wholesale cell phones market. Now a days, cell phone chargers also having it's solar power for charging. As per the survey of one powerful media, the users of wholesale iphone accessories are nearly 1,484,232,448 present. So, how is it possible to imagine World without cellphone? Can you?
