iPhone 6s Force Touch Display
iPhone 6s rumors leading into August suggested that Force Touch would be one of the key differences between this year's iPhone and the iPhone 6.
Earlier this month, 9to5Mac's Mark Gurman outlined the feature in detail and at this point, there's reason to believe that Apple's Force Touch technology will be included with this year's iPhone.
If you're not familiar with the feature (it's found on the Apple Watch and new MacBook), it will allow iPhone users to utilize pressure-sensitive gestures. In turn, these gestures will allow iPhone 6s users to take advantage of app shortcuts.
While the feature is interesting, some believe that it will serve as a small piece of the iPhone 6s and iPhone 6s puzzle.
