I've not bought an iPhone since 2012, but Apple could win me back in one key area

I haven't used an iPhone as my daily device since 2012. That was the iPhone 5, renowned for its stunning industrial design, including, amusingly, the squared metal edges not too dissimilar to the latest iPhones.

The iPhone 5 offered a 4-inch display, while the same year saw the launch of the Samsung Galaxy S III, the HTC One X, and the Nokia Lumia 920. Each of these devices had a larger display, with an exciting feel to Android and Windows Phone compared to iOS 6 and its dated skeuomorphic design.

It felt, at the time, as though the innovation in phones wasn't coming from Apple.
