Not known by many people, the first laptop computers were widely used as early as the late 1980s. These portable computers were more or less specifically catered to businessmen who continuously need to keep their documents and manage their files on the go. During the past three decades, intensive computer research and development have provided astounding innovations to this technology. In the past, laptop computers were still a few inches thick and some of them may weigh up to 15 pounds. Newer versions of laptop computers are not only slimmer and lighter but they are now also faster, more powerful, and well-suited to our different needs.
