Frog Design and Apple

"Apple execs often say they're as proud of the products they don't release as they are of those they do - and if you'd like to take a look at some of those unreleased prototypes, then good news for you in form of a new book from influential designer Harmut Esslinger of Frog Design."

Frog Design was responsible for the 80's designs for many of Apple's products, including the Apple IIc, and they really came up with some interesting designs. According to Esslinger, they worked very closely with Jobs on much of what they did come up with during that period. The book is called "A Fine Line: How Design Strategies Are Shaping the Future of Business" and has background along with pictures of known and previously unseen products. There really are some interesting products shown in this book, some of which they probably could sell now.
