|HP's Folio 13 Ultrabook|
Chip-maker Intel defined the notion of Ultrabooks, laying out a spec that uses its latest processors, maximum weight of 1.4 kilograms, a no-moving parts solid state disk drive and a very thin chassis that resembles Apple’s tiny MacBook Air.
Several manufacturers have hopped on the Ultrabook bandwagon, including HP with its $1199 Folio 13. The Folio weighs 1.5kg (some people cheat the spec a bit) , boasts a 13.3 inch screen, 128GB drive and is about 1.8 cm thick.
The ASUS ZENBOOK is another contender, starting at $1599. The extra dough buys you a machine just .89cm wide, 1.1kg in weight and capable of firing up the operating system in two seconds.
The thin and light nature of ultrabooks means they are marketed towards folks who value style as well as speed. The ASUS video below is typical of the stuff we're seeing for Ultrabooks.
