At the iPhone 6 event in California, Apple's 'one last thing' was the reveal of the new iWatch. As expected, the iWatch is a round-faced smartwatch that pairs with your new iPhone 6 (or any other modern iOS device with Bluetooth), while providing all of the usual health-tracking functionality of other smartwatches via a bevy of clever sensors. There is a sapphire glass front panel to prevent any wear and tear, and NFC and digital wallet support so that you can pay for things using just your smartwatch.
