[citation][nom]Travis Beane[/nom]How about aluminium oxide? I think sapphires are pretty hard. Synthetic sapphire glass is hard, but brittle. Scratch resistant, but it can still shatter. I've succeeded in scratching gorilla glass, but hey, it's never shattered after numerous drops.[/citation]
There are a few watch manufacturers that use sapphire as glass, usually the ones that cost a small fortune and reside on the wrists of rappers or basketball players, but it is certainly already commercially used and would be ideal for phone use.
Problem is the cost involved, but the fact that sapphire glass can't be patented and if is was rolled out across the whole cellphone industry the costs would drop dramatically, let's get it done!
