The Wall Street Journal is reporting that the much-rumored 12.9-inch iPad is being delayed by Apple because of high demand for the new iPhone 6 Plus. The newspaper claims that, while production of the jumbo tablet was slated to begin in December, Apple isn’t satisfied with the rate at which the iPhone 6 Plus is being manufactured. A source at a supplier told the Journal: “The top priority for the supply chain is to meet the overwhelming demand for the larger screen iPhones. The output of the 5.5-inch iPhone 6 Plus remains unsatisfactory. It would be challenging for display makers to split resources and spend a few months to ramp up production for a new larger screen iPad now.” The report also claims that Foxconn is struggling to hire enough staff to put together the new iPhones at its Zhengzhou plant in China, which is contributing to the problem.
