ULTRABOOKS
Ultrabooks are a relatively new breed of stylish, lightweight laptop that may within a few years replace most larger and heavier models. To be called an ultrabook, a laptop has comply with a hardware specification laid down by Intel. This requires laptop manufacturers to shrink their computers to less than 21mm thick, to make them resume from sleep in just few seconds, to provide at least five hours of battery life, and to include anti-theft technology. Many ultrabooks also use a solid state drive (SSD) rather than a traditional, spinning hard disk, weigh not much more than a kilogram, and are housed in a designer casing made from a material such as an aluminium alloy or carbon fibre.
