A carbon fiber shell would fit with the invitation's assertion that the X11 is the "lightest notebook on earth." Interestingly, the X11 isn't referred to as an ultrabook. Perhaps it's not thin enough to meet Intel's requirements—or maybe it has AMD hardware under the hood. We'll know for certain on May 31, which is when Gigabyte plans to unveil the X11 to the press.However, as The Tech Report points out, focusing on the weight of the laptop may not be a smart design move. Most users probably prefer a bit more battery life rather than a notebook that weighs an ounce less.
The launch event is being held in the week before the Computex trade show in Taipei, Taiwan. Evidently, Gigabyte doesn't want its new baby getting lost in the flurry of news that accompanies the show.
