Just when you thought Asus had learned from its past experience with netbooks that launching a myriad of confusingly named devices was not helpful to consumers, they decide to do it all again with the Zenbook brand and the U500. Up until now, the Zenbook line has shared two specific things; first, all Zenbooks featured a similar wedge shaped design and metalic finish. Second, all Zenbook’s were Ultrabooks. Until now, that is. Asus has decided to throw the U500, a 15″ thin and light laptop, in with the rest of the Zenbook branded computers. While we would have preferred Asus didn’t dilute the shared features of the Zenbook brand, that’s not to say that the new U500 thin and light is not shaping up to be a solid Ultrabook alternative.
