Fujitsu will this month launch a super-thin Ultrabook, built on Intel's latest Haswell processors, with an 11-hour battery life and a screen with nearly three times HD resolution. The company said the new "UH90/L" model from its Lifebook line will be the world's thinnest for a laptop with a hard disk drive, measuring 15.5 mm at its thickest point. It will mark Fujitsu's entry into the quickly growing ranks of PCs built around Haswell processors, which boast slightly improved performance along with reduced power requirements.
