Apple Inc. misleads consumers about the amount of storage space used by its iOS 8 operating system in iPhones, iPods and iPads, two users claimed in a suit targeting the software, adding a new wrinkle to a product introduction that has been riddled with hiccups, snafus and missteps.

Apple, the world's most valuable technology company, doesn't tell users that "as much as 23.1 percent of the advertised storage capacity of the devices will be consumed by iOS 8," the two Florida men claimed in a suit filed Wednesday in San Jose, California, federal court. Apple uses the space shortage to drive consumers to its fee-based iCloud storage system, they said.

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's or grandchild's recital, basketball game or wedding," Paul Orshan and Christopher Endara said in their complaint. The men seek to recover millions of dollars on behalf of a nationwide class of Apple's mobile-devices users.
