If Alexander Graham Bell were alive today he would be amazed. It wasn't that long ago when he made the first telephone call to his assistant from another room in his laboratory. At the time they had been working on a device to help deaf people hear. Bell patented the telephone in 1876. Now, 130 years later, people are walking around with tiny but powerful computers held to their years. These wireless devices can be used to browse the Internet, play games, text message, manage schedules
