The 1992 Toshiba T4400SX was the first notebook to offer a choice of screens: a bright page-white LCD screen, or the latest super-fast plasma screen technology. The benefits of the plasma screen are brighter images and a much faster response. The speed of plasma allows you to work in advanced applications and in particular with graphics just as you would on a desktop. With the T4400SX even moving images won't blur on your screen. And the screen is unexpectedly large for a notebook, too. Try a diagonal of 9.5 inches (24 cm) for size.
