iPhone 5S to come with a “killer feature”
With the new improvements in both hardware and software coming in from various Android manufacturers and further pressure coming in from both Windows Phone 8 and the newly launched BlackBerry Z10, Apple simply cannot sit back and rely on customer loyalty and a better design. As such, iPhone 5S is expected to come with loads of new features since the "S" lineup of iPhone's rarely ever came with a hardware refresh.
To that end, Morgan Stanley analyst Katy Huberty dropped a very interesting piece of information in a recent interview with CNBC as pointed by BGR. After a meeting with Apple's CFO Peter Oppenheimer, Huberty said that, “Apple will surprise this year” with “a killer feature that drives consumers increasingly to the platform” and that this “killer feature” will likely increase “the value of those 500 million [Apple] accounts.”
No idea on what the feature is, but clearly given the last part of that statement, the new feature won't be limited to just iPhone 5S and will likely be released across the entire iOS device range; at least the current-gen devices.
