The saga of Apple's disappearing sapphire screens seems to have finally offered some concrete answers. According to a recent article by the Wall Street Journal, the screens' supplier, GT Advanced Technologies, wasn't just mismanaged: the product they were putting out was pretty much unusable.
Not that that's entirely GT's fault, of course. After all, Apple was asking a lot of the company. According to the Wall Street Journal:
The Apple-GT marriage was troubled from the start. GT hadn't mass-produced sapphire before the Apple deal. The New Hampshire company's first 578-pound cylinder of sapphire, made just days before the companies signed their contract, was flawed and unusable. GT hired hundreds of workers with little oversight; some bored employees were paid overtime to sweep floors repeatedly, while others played hooky.
All of which is a major problem in its own right, but add in the fact that Apple already uses "one-fourth of the world's supply of sapphire to cover the iPhone's camera lens and fingerprint reader" alone, upping that supply to cover screens is bound to exacerbate any pre-existing problems.
