"Apple’s misrepresentations and omissions are deceptive and misleading because they omit material facts that an average consumer would consider in deciding whether to purchase its products," the complaint says. "Rather ironically, Apple touts iOS 8 as 'The biggest iOS release ever.' Of course, Apple is not referring to the literal size of iOS 8, which appears to be entirely undisclosed in its voluminous marketing materials extolling the purported virtues of iOS 8."
According to the complaint, the out of the box size discrepancy works out like this on some of Apple's newer devices, ranging from 18.1 to 23.1 percent:
"Using these sharp business tactics, [Apple] gives less storage capacity than advertised, only to offer to sell that capacity in a desperate moment, e.g., when a consumer is trying to record or take photos at a child or grandchild’s recital, basketball game or wedding," it says. "To put this in context, each gigabyte of storage Apple shortchanges its customers amounts to approximately 400-500 high resolution photographs."
Apple, which is not commenting on this complaint, been sued over this before, notably over the amount of advertised storage in iPods in 2007 (which was ultimately dismissed). The big difference there is that the complaint was lodged over an 8GB iPod Nano only having 7.45GB of usable storage, which is just a 7.5 percent difference. It could be far worse. Microsoft was sued over the amount of available amount of storage in Surface, notably when users only had access to about half the storage on its earlier models.
