TechwareLabs takes a look at the Asus Zenbook Prime UX31A Ultrabook running under Windows 7 and 8

“Ultrabook” is one of those phrases that has lost much of its meaning over time. When Intel initially dreamed up the concept, they were looking to see Windows-based competitors to the Macbook Air. What manufacturers delivered has varied so widely in price, features and finish that “Ultrabook” can mean just about anything. Asus, however, seems to be cleaving close to Intel’s original intent; the Zenbook Prime UX31A looks at first glance to be a slick competitor to Apple’s featherweight offering. First impressions can be deceiving, though, so we’re taking a closer look to see if this little slice of Zen lives up to its promise.
