Exactly how thin is it, you might ask? At just 2.9 lbs and 0.5 inches, it's thinner and lighter than its competitors, but that's not too surprising considering the Aspire S3 Ultrabook is a featherweight next to, well, pretty much everything. It's dwarfed by dogs, wisp-like compared to a copy of War and Peace, and positively spindle-shanked beside a slice of Sicilian pizza.
