Apple may use super-strong sapphire screens on its iPhone 6 and iWatch, a new rumour suggests.
According to Canonical's CEO Mark Shuttleworth, Apple has just bought up enough sapphire screens to last about three years.

This isn't the first time we've heard about Apple buying the screens - which are made of the second-strongest material on earth after diamonds. The initial news came from supply chain rumours, but whether it was meant for the iPhone 6 or iWatch wasn't clear.
According to Shuttleworth: "Apple just snapped up the entire three-year supply of the same sapphire display we wanted for the Edge." The Edge would have been a 4.5-inch device, had it reached its crowdfunding goal.
Of course this is based on Shuttleworth's comment so we must ask if the three-year supply is based on the usage of Canonical or Apple, which would clearly demand a lot more. Also the iPhone 6 will presumably be 5-inches so the 4.5-inch Edge screens wouldn't fit. But since it can be cut to size these may still appear on both the iPhone 6 and iWatch.
While we're at the rumour stage right now, sapphire displays - which won't be easy to scratch - appear to be coming soon.
