History of laptops
Laptops began from a desire to have a full-featured computer that could be easily used anywhere. These all-in-one systems could be easily transported, but were heavy and usually were not battery powered. The cathode ray tube (CRT) was one of the major reasons portable computers were so large and heavy, but the use of a full-size desktop motherboard with room for ISA expansion cards was another size factor.
It was the transition to LCD and plasma displays that permitted the luggable to shrink in size and become the first real laptop, though at first still without internal batteries. Battery technology improvements and the introduction of smaller devices such as the 3.5-inch floppy disk permitted a gradually more compact and sophisticated complete portable system.
