Before 1975, a computer is not carryable like today. They are bulky.
IBM launched the first portable computer IBM 5100 in 1975 which weighs around 50 pounds. It is available in 12 models having storage variations of 16K, 32K, 48K, and 64K. It costs between $8000 to $20000 then.
It is the second personal computer from the company IBM, after IBM 5150. The size of this portable device is slightly more than a typewriter. That’s why it is carryable even though it weighs high.
After this launch, there were computer engineers who were trying to develop computer technology. As a result, the launch of the product Epson HX-20 in 1980, and the R2E CCMC Portal in 1980.
In 1981, Adam Osborne launched the fully portable computer in the architecture of a laptop. It weighs around 25 pounds (half of the IBM5100). Because of his invention, the computer was called Osborne 1.
Here is the image of Osborne.
From then computer technology changed a lot. Companies keep on improving technology. As a result, reduction in cost with performance improvement.
Today, the computer is a must-required device in almost every field. To find out how helpful a computer is to you, go through the link.
