The Epson HX-20, released in 1982, is recognized as the world’s first truly portable, notebook-sized computer, “the first laptop”, featuring a full keyboard, built-in LCD display, integrated dot-matrix printer, and rechargeable batteries that allowed up to 50 hours of use on a single charge. Its claim to fame was pioneering the “laptop” form factor, compact and lightweight (about 1.6 kg, A4-sized) with all essential computing features, making it a forerunner of modern mobile PCs and earning it the title of “the fourth revolution in personal computing” by BusinessWeek. It sold a remarkable quarter of a million units worldwide and was influential in shaping future portable computers.<\/p>\n\n\n\n
