So according to reports it looks like Apple may be looking to replace the Gorilla Glass on its devices with Sapphire. At the moment Sapphire glass is 10-30 times more expensive than Gorilla Glass from Corning, however, it appears that Apple has invested heavily in the development of the production process of Sapphire glass (which is already used for the home button on the iPhone 5s).
Apple has made a deal with the manufacturer, GT Advanced Technologies, and together with a Solar Panel Company Apple acquired to access its Ion Particle Accelerator technology, it will be able to manufacture the thin slices of sapphire at a much lower price. This may mean that before long the entire screens of our devices will be super hard waring.
Personally, I look forward to the day that I don’t have to apply one of those awful bubble blighted screen protectors.
