Lenovo's upcoming ThinkBook Aeroblade, though, may take things to a whole new level. Another hint at the shrinking vertical dimensions of this laptop design is the flat-key keyboard. This could be a new class of laptop for Lenovo, which has experimented with laptop form factors, such as the dual-screen ThinkBook design that we found particularly intriguing. It's possible that Lenovo is gunning for the thinnest laptop award with this device, and if we were only measuring from the leading edge, it may well have won it. However, laptop thickness is usually measured at the broadest point, so we'll have to see what the underside of this laptop looks like before drawing any conclusions.
