Samsung shows off super-slim smartphones

Samsung's X820 smartphone is just 6.9mm thick

Samsung has been showing off two mobile handsets which it claims are the slimmest in the world.

The new X820 smartphone is just 6.9mm thick, about the same as an iPod Nano, and weighs just 66g. It comes with a 2-megapixel camera and TV output port, and will be released across Europe this summer.

The second handset is claimed to be the world's thinnest slider phone, at just 13mm and 93g. The D900 comes with a 3-megapixel camera and removable storage.

"Ergonomically designed to become one with the user, Samsung's slim phones deliver the perfect harmony of comfort, simplicity and sophistication," said Kitae Lee, president of Samsung's telecommunication network business.

"Samsung's ultra-slim phones are dedicated to bringing people together. With its exceptional design and thinness, the X820 will become one with the user, one with others, and one with the world."

Phones have been getting steadily slimmer over the years as chipsets have shrunk and new battery technologies like lithium polymer units have allowed designers more flexibility.

The popularity of Motorola's Razr handset has shown a strong demand for the slim, light handset.
