NEC's LaVie Z Ultrabook has definitely lost weight
 

No one complained when we reported NEC's initial claimed weight of 999 grams (2.2 pounds) for its LaVie Z Ultrabook, but it turns out that statistic is brutally unfair. The 13.3-inch laptop actually tips the scales at just 875 grams (1.9 pounds) thanks to the magnesium lithium alloy used in its 0.59-inch chassis -- not bad when you consider that there are still 1.3kg netbooks wandering the planet. Of course, in line with Intel's official Ultrabook spec, you're getting a minimum Core i5-3317U processor (yes, that's Ivy Bridge) and 128GB SSD, plus USB 3.0, SDXC slot, HDMI out and a claimed battery life of 8.1 hours. There's no word on US pricing yet, but that base spec will set you back ¥130,000 ($1,600) in Japan, while the top model with Core i7-3517U and 256GB SSD will add another ¥30,000 ($375) to your bill.
