Engadget: "Like we mentioned in our hands-on impressions, the new Z-series laptops from Sony are in many ways impressive, but in ultimate thinness they leave a bit to be desired. This is perhaps best demonstrated best by Journal du Geek's comparison shots here with the MacBook Air. Sure, the Z wins all over the place on specs, with Centrino 2, discreet graphics, a full-size laptop hard drive bay, and what was that? Oh yeah, a Blu-ray drive. The Z also manages a smaller footprint, thanks in part to a smaller 13.1-inch screen in that shorter 16:9 aspect ratio, but also due to its slim bezels surrounding the screen and keyboard -- something the Air could do well to take note of -- but the actual 1-inch thickness seems dramatically fat compared to its ultrathin competition."
