The thinnest laptop computer is the Windows 7 Dell Adamo XPS, which ranges between 9.7 mm (0.38 in) at its slimmest point to 10.3 mm (0.41 in) at its thickest – an average of 9.99 mm (0.39). The Adamo stays skinny by relocating key components and tucking the keyboard inside the reinforced 13.4-in display enclosure when closed. It measures 340 x 273.9 x 9.99 mm (13.39 x 10.78 x .39 in)

Equipped with a 1,366 x 768 pixel widescreen 16:9 display, the laptop weighs 1.44 kg (3.2 lb), making it one of the world’s lightest laptops. Retail price: $1,999.99.
