Apple Prototypes by Frog design founder Hartmut Esslinger

Early Apple Design by Esslinger

Love the design prototypes of the 80's !
As our digital gadgets are more and more differentiated by their design and less by their technology, we'll probably see some retro future design smartphones and tablets soon.

The Verge has a nice article and lots of foto's of 80's design prototypes of apple equipment:
"Apple's focus on design has long been one of the key factors that set its computers apart. Some of its earliest and most iconic designs, however, didn't actually come from inside of Apple, but from outside designers at Frog. In particular, credit goes to Frog's founder, Hartmut Esslinger, who was responsible for the "Snow White" design language that had Apple computers of the ’80s colored all white and covered in long stripes and rounded corners meant to make the machines appear smaller."
