If you had any doubt that the Samsung Focus was well built, it has been our understanding that the Focus uses Gorilla glass for it's screen.  This has now been confirmed by Samsung (via Twitter) that the screen is indeed Gorilla Glass.

What is Gorilla Glass? As the name implies, it's a thin, light-weight, durable glass that is as tough as a gorilla. As described by Corning,

"Gorilla Glass is an environmentally friendly alkali-aluminosilicate thin sheet glass designed specifically to function as a protective cover glass for high-end display devices such as notebook PCs, televisions and mobile phones."

Now this doesn't mean you can throw caution to the wind and drag your Focus across a bed of nails and not expect to see any scratches. It does mean that the Gorilla glass offers a little more scratch-resistance and durability than your average screen and quit possibly eliminates the need for screen protectors.
