3. iPhone Air
What happens when you lock a Macbook Air and an iPhone in a room? Nine-months later out pops this beautiful design. Incorporating the tapered edge of the Macbook Air and much loved simple lines of the iPhone 4S to give birth to a device that is as elegant as difficult to produce. The slimness of the device would almost definitely limit either battery life or processor power. Sacrificing either for the sake of aesthetics is not something we imagine Apple would entertain, so whilst we love the design, unfortunately it probably won't come to fruition in the next iteration of the iPhone.
