Samsung Galaxy Tab comes with its own Gorilla

Scratch resistant runs on a banana
It provides a protective cover sheet for Galaxy Tab without getting in the way. The Gorilla glass provides damage resistance, improves the lifespan of portable display devices and offers a more scratch-resistant, durable and pristine viewing quality.
The glass is made by Corning Korea Company and is 'new technology' as far as the touch screen goes. However it was first developed during the Cold War. But the bendy tough glass failed to take off until it started to be tested in some of the more expensive smart phones.
