when was the first laptop introduced to the public
History of laptops The Osborne 1 is considered the first true mobile computer by most historians. Adam Osborne founded Osborne Computer and formed the Osborne 1 in 1981. The Osborne 1 had a five-inch screen, incorporating a modem port, two 5 1/4 floppy drives, a big collection of bundled software applications, and a battery pack. The computer company was a failure and did not last for very long. Although it was large and heavy compared to today's laptops, with a tiny 5" CRT monitor, it had a near-revolutionary impact on business, as professionals were able to take their computer and data with them for the first time. This and other "luggables" were inspired by what was probably the first portable computer, the Xerox NoteTaker. The Osborne was about the size of a portable sewing machine, and could be carried on commercial aircraft. The Osborne 1 weighed close to 11Â kg and was priced at $1795.
MacBook Air Apple incorporated several features in the design of the MacBook Air, such as the reduction of lead to make it more environmentally friendly. The MacBook Air contains no BFRs and PVC wiring, meets Energy Star 5.0 requirements, has a recyclable enclosure, and is rated EPEAT Gold. Its display is made from arsenic-free glass, and contains no mercury.[7][32] To reduce the computer's size and weight, several features were sacrificed. It was Apple's first notebook since the PowerBook 2400c without a built-in removable media drive.[33] It also omits a FireWire port, Ethernet port, line-in, media card slots (except the 13" 2010 through 2015 models, which have an SD card slot), and a Kensington Security Slot.[34]
