Adamo (Latin for "I fall in love with") is a Dell subnotebook focused on design and mobility. A notebook prototype was unveiled at the Consumer Electronics Show on January 9, 2009. Dell also claimed it is the "world's thinnest laptop", at 0.65 inches thick. It is a slim luxury ultraportable intended to compete with Apple's MacBook Air, Lenovo's ThinkPad X301, or HP's Voodoo Envy 133 laptop. On September 9, 2009, Dell previewed a new, thinner Adamo "XPS" laptop design, which was 9.99 mm (0.39 inches) thick. It is the world's thinnest laptop, almost half as thick as the thickest part of the MacBook Air.

On September 9, 2009, Dell previewed a new, thinner Adamo XPS laptop design, which was 9.99 mm (0.39 inches) thick. It was released on November 5, 2009 and priced at (USD)$1,799. The laptop's bottom half, containing the keyboard, is smaller than the top half of the laptop containing the screen. The screen half is concave, so when shut the keyboard embeds itself into the screen. It is designed, that when open, the bottom of the screen half and the edge of the keyboard, make contact with the surface it is resting on. The Adamo XPS has a heat-sensing strip on the lip of its lid which, when touched, opens the lid. Internally, it has either a 128 GB solid-state drive or a 180 GB hard drive. It uses 4GB of DDR3 memory and a 1.4 GHz Intel ULV (ultra low voltage) processor. The battery can run either 4 or 5 hours, depending on configuration.

In March 2010, Dell discontinued their Adamo XPS line.

During that same month of March 2010, Dell has made Adamo XPS available again.
