Asus will offer what it claims to be the thinnest and lightest notebook PC with a 15in screen, the company said this week at the Cebit trade show here.

Some versions of the V6800V series will be as little as 0.9in thick and weigh 2.5kg.

Different versions of the V6800V series that have a more powerful battery will fit in the same casing, but weigh a little more at 2.6kg.

The smaller 4-cell battery will enable the notebook PCs to operate for about four hours, while the versions with the larger 8-cell battery should allow about eight hours of operation, he says.

All of the V6800V series models will come with the latest version of Intel's Centrino technology, code-named Sonoma. Centrino is a combination of the Pentium M processor, the Alviso chip set and an 802.11 wireless chip.

The notebooks will be available with various Pentium M processors with three different clock speeds starting at 1.73 GHZ.

"These are small and light notebooks that are nearly as powerful as desktop [PC] replacements," a company spokesperson said.

An entry-level version has a 60GB hard drive, while other versions will have 80GB hard drives. The company is considering adding 100GB hard drives for later versions.

Different specifications will be available for versions of the notebook sold in different European countries, but the company doesn't plan to sell the light version in Germany.
