Designer Hartmut Esslinger and his firm Frog Design was responsible for many of Apple's designs in the 1980s, and he decided to publish images of some of the concepts that got nixed in his book "Ingeniously Simple - The early years of Apple design." We got a hold of some of these images, and rounded them up to get a look at some of the advanced foresight happening at Apple decades ago.
Turns out these guys were already thinking about concepts that resemble the iPad, iPhone, and even the iWatch thirty years ago.
