Toshiba plans to claim the crown of the world's thinnest and lightest 13-inch notebooks, a leak may have revealed today. The system would use a full-power Core i7 processor but would use exotic cooling and construction to get as thin and light as Apple's MacBook Air or Dell's Adamo XPS. It would use a system known as "Mountain Blaze" to lower heat and would be made out of a unibody, honeycomb structure that would keep it stiff even at its thin dimensions.
