Laptop Evolution
By Edgar Tyskevic
• A laptop computer is a personal computer for mobile use. A laptop integrates most of the typical components of a desktop computer, including a display, a keyboard touchpad and speakers into a single unit. A laptop is powered by mains electricity via an AC adapter, and can be used away from an outlet using a rechargeable battery. Laptops are also sometimes called notebook computers or notebooks.
The First Laptop Computer - Osborne 1• Introduced: April 1981• Price: US $1,795• Weight: 24.5 pounds• CPU: Zilog Z80 @ 4.0

The second laptop computer - Epson HX-20 with built in printer
• Also released in 1981, was the Epson HX-20, a battery powered portable computer, with a 20-character by 4 line LCD display and a built-in printer.
• In January of 1982, Microsoft's Kazuhiko Nishi and Bill Gates begin discussions on designing a portable computer, based on using a new liquid crystal display or LCD screen. Kazuhiko Nishi later showed the prototype to Radio Shack who agree to manufacture the computer.
