Come to think about it, when the Apple Watch gets a cellular chip the iPhone will become obsolete. People will instead buy an iPod Touch which then does the same thing the iPhone does now, especially after yesterday's incredible hardware upgrade. The only thing then that sets the iPhone apart from the iPod is Touch ID and the larger screen and I assume many people won't care all that much about those features if they can save a lot of money. Since the iPhone is Apple's largest cash cow (92% of all smartphone profits worldwide are made by Apple) and the impact a cellular chip in the AW will have I highly doubt the likability of this upgrade. Any thoughts on this?
