Gorilla Glass. My Cowon S9 has the stuff, it's pretty awesome actually.
But why not just use aluminum oxide? Sapphire glass is something I want so bad on a phone.
The iPhone 4 seems extremely fragile to me now. Both my phone and PSPgo have taken some pretty nasty hits (slammed down into concrete, 10 foot fall onto stone, being in the same pocket as my keys etc.).
