Apple iPhone 5S

We know there will be a new iPhone from Apple in 2013, and on past form it will likely be called the iPhone 5S, though there's no word on the new killer feature. Upgrading from the iPhone 4 to the iPhone 4S saw the arrival of Siri, and while moving from the iPhone 5 to the iPhone 5S will undoubtedly herald a new, faster processor, there is pressure to add something genuinely exciting; sales of the iPhone 5 have been slower than expected, with many shoppers happy enough with the iPhone 4S.

So new features on the iPhone 5S that revive the iconic product line are a must, such as Retina+, a front camera with facial recognition, multiple colour options, and a jump up from the 8 megapixels of the iSight camera. Expect to hear about NFC (Near Field Communications) compatibility, the inclusion of which ought to give a fillip to smartphone payment tech in cities across the world, though Apple could controversially introduce its own version.

Instead of the usual year-long wait it's possible that Apple will swap to a shorter product refresh term in order to squeeze out the iPhone 6 in 2013, too.
