Hot on the heels of the super thin Macbook Air is the Asus Zenbook. I finally saw the laptop in a retail outlook and can tell you it is indeed super thin. I was really impressed with the design, and more importantly with the finish of the product. This is the first of the Windows notebook that is ultra-thin with a metallic shell. Certainly on the surface, it looks really impressive. But I wonder, can it live up to some of the really impressive qualities of the Macbook Air like battery life, instant on, etc. I’m not sure. But I will say, I’m definitely tempted by this as Windows computer.
