Before launching a product, Apple and almost all other companies in the industry test various prototypes and try to turn numerous ideas into reality. However, they are not always good enough to be launched or other factors prevent them from filling the store shelves.
The website Designboom published some images from the book "Design Forward", by Hartmut Esslinger. In them, we can see several Apple prototypes built in partnership with Frog Design, a company founded by Esslinger in the 1980s, that never saw the light of day.
Below, check out some images:
"Macintosh Studies", 1982.
?Tablet Mac?, 1982.
"Baby Mac", 1985.
