Laptop, 1982

A sturdy lap was required to support the earliest portable computers. The Osborne 1, released in 1981, often stakes a claim as the first laptop but it looked more like a sewing machine than today's sleek machines, and tipped the scales at more than 10kg. Introduced a year later, the GriD Compass 1100, designed by Brit Bill Moggridge, is a more likely contender. It was the first laptop to sport the now standard "clamshell" case and its lightweight build (5kg) made it a hit with Nasa and US paratroopers.

Sewing machine, 1830

Humans had used bone and horn to sew for tens of thousands of years, but the first patent for a machine that could do it without the need for such cumbersome devices as pins and thimbles was submitted in 1790. It didn't work. The first functioning machine was invented by Frenchman Barthélemy Thimonnier in 1830, but his machines were destroyed in riots. In 1845, Elias Howe built the contraption that would spawn the modern day machine, including those built by one Isaac Merritt Singer.

A year later, the German naturalist Conrad Gesner described a wooden writing tool that contained the substance. Nicolas Conté perfected the pencil more than a century later by mixing graphite with clay and gluing it between two strips of wood.

Digital watch, 1972

Watches made the short journey from bosom to wrist during the 19th century, due in part to the craze among middle-class women for cycling. Their new, more convenient position made sense and they developed quickly. Rolex made the first waterproof watch in 1926 and a year later the ultra-accurate quartz-crystal controlled clock arrived. Watches finally went digital in the 1970s when the Hamilton Company developed the Pulsar, which sported lights in place of hands; the liquid crystal display (LCD) followed in 1977.
