The concept of a portable computer has evolved significantly since the late 20th century. The first true laptop is often credited to the Osborne 1, introduced in 1981. It was bulky by today’s standards, weighing around 24.5 pounds, but it set the stage for future innovations. IBM’s ThinkPad line in the early 1990s and Apple’s PowerBook series significantly shaped the laptop market.
