Apple has enough money to buy 298 million iPhones (from itself, presumably). Stacked back to back, the iPhones would reach 1,300 miles into the sky -- well into outer space.
In a hypothetical world where Apple would pay itself for its own gadgets, Apple could buy 967 million iPods, 430 million iPads, 148 million of its new ultra-thin MacBooks and 11.4 million Apple Watch Editions.
