A short video shows in a simple way the development of mobile devices from 1973 until today. Motorola's first prototype weighed as much as 1.1 kilograms and needed 10 hours of charging for 30 minutes of talk time, which was its only function.
Today, there are thousands of different models available on the market with a variety of useful functions, and the number is expected to grow exponentially with the development of technology. An insight into the future of mobile devices was recently presented by Google with its the Tango project.
