The mobile phone was a revolutionary invention. Without the constraint of wires, telephone users were free to make and receive calls on the go. It had an incalculable effect on both personal and business life by allowing its owner to close a big sale and then reach the babysitter, all while sitting in bumper-to-bumper traffic.
Traditional cellphones, which simply make and receive calls, are now being crowded out of the marketplace by smartphones, specifically Apple’s iPhone. This device not only makes calls but sends and receives emails, plays music and videos, takes pictures, and supports myriad applications. The standard cellphone has since experienced a marked decline in sales, while the iPhone and other so-called smartphones have seen steady increases.
