AnUltrabook is a category of notebook PCs that conform to a certain standard.
After the introduction of tablet PCs to the market,Intel began to push a concept of an ultra-thin, ultra-light, but powerful notebook to compete with tablets; an Ultrabook.
Tablet PCs mostly use microprocessors developed by Intel rival ARM holdings (though manufactured by licensees). With Tablet PCs posing a serious threat to notebook PCs, and therefore to Intel's interests in the market, Intel put up millions of dollars in funds to develop the technologies to make Ultrabooks, and importantly, to make them affordable to consumers.
An Ultrabook aims to be about as thin as a tablet PC and no more than 1.4kg in weight. It must include a solid-state drive (SSD) as opposed to a traditional hard disk drive. It does not contain an optical drive.
