It's feels like a long time since Apple has released a product that is truly transformational. The iPod may not have been the first mp3 player, but it was the catalyst for changing the way that we listen to music. When the iPhone launched, it's fair to say that it changed the world of mobile phones forever, ushering in the era of the smartphone as we know it. Since then however, there haven't really been any products that have changed the game. The iPad wasn't a huge leap; it's really just a big smartphone, and the Apple Watch is a great device, but not really groundbreaking.
