ultraportable
(ul´´-tra-p��rt´&-b&l) (n.) A class of laptop computer that is designed around its portability. Ultraportables typically weigh less than four pounds and, when closed, are 1.5″ thin or thinner. A common ultraportable also will have wireless networking capabilities, can have an internal optical drive, and capabilities to connect to an external storage device. Since the devices are designed to be compact and easily portable, the keyboards tend to be smaller than those of a typical laptop and the batteries are designed to be small and lightweight, creating what some view as drawbacks to the ultraportables: uncomfortable ergonomic design and short battery life.
The IBM ThinkPad X40, Sony VAIO PCG-TR3A, HP Compaq NC4010 and the Gateway M200X are examples of ultraportable laptop computers.
