Very cool. I don't buy the unbreakable part. Even a diamond will break or shatter if it is hit in the right spot. I worked in the jewelry business when I was a kid. There are a select few that set diamonds simply because of the fact that even when you know what you are doing stuff happens.
The real point that is exciting is phones and tablets will have a lot more protection against scratches and if you manage to break the screen it was probably cause it was run over by a bus.
