Mobile device history
Laptops became one of the first mobile computing devices by eliminating the wires between the computer and its peripherals, then integrating them into one unit. The first laptop, or portable computer, was the IBM 5100, released in September 1975.
Today, mobile device usually refers to any hand-held computer capable of running apps that can connect to the Internet wirelessly. However, even by today's more scrupulous standards, the category keeps expanding with new inventions. As is true in any branch of computing, our mobile devices continue to offer more advanced functions while reducing size and weight.
