NEC's 13.3-inch LaVie Z Ultrabook weighs just 2.2 pounds

Just in case you thought NEC was done with its PC updates this week, the Japanese PC builder has thrown its hat into the Ultrabook ring with a unique contribution of its own. The LaVie Z has a 13.3-inch screen like your garden variety ultralight, but it weighs just 2.2 pounds through a new lithium-magnesium alloy shell about half the weight of the aluminum that some companies love to use. Unfortunately, that weight and the slim frame are about all we know so far: NEC isn't providing any internal specifications, possibly because it's waiting on Ultrabook-ready Ivy Bridge chips. Even so, if you're hanging around Japan and want the lightest possible laptop you can get at a 13-inch screen size, the wait until the planned summer release will feel like an eternity.
