Hm. Well, that's a mighty quick fall from grace for a company that could have rocketed to the top if its screens had been used in the iPhone 6 and 6 Plus. That's tough on investors and the individuals that lead GTAT, for sure. Sapphire displays are a great technology, but now just doesn't seem like the right time for them, and that lack of adoption has killed GTAT for now.
