In an industry where ultrabooks are starting to gain momentum in mainstream adoption, we guess we’re not surprised to learn that NEC has outed a new ultrabook of their own. Dubbed the LaVie Z, this is an ultrabook by NEC that has gone with the use of magnesium alloy over the preferred aluminum material for its chassis. We’re not sure how much more sturdy it will be compared to its aluminum counterpart, but if you’re in the market for a light and thin ultrabook, NEC claims that magnesium alloy is 50% lighter than aluminum, making the LaVie Z a truly portable solution. So what sort of specs are we looking at here? Unfortunately NEC has deigned to offer up all the details of the device but what we do know is that it will feature a 13.3” display, weighs 999g and is expected to be made available in Japanese markets this summer. We expect more details of the LaVie Z to surface at a later date so be sure to check back with us then for more info.
