Amy-Mae Elliot has written an article about the evolution of the Apple Mouse. Her article includes fantastic pictures along with details, the highs and lows of each product.
Quoting a piece of Amy’s article;
The evolution of the Apple mouse makes for an interesting design journey that includes the loss of its tail, moving from a single button to touch, and of course going from beige to multi-colored and back to a monotone.
Well worth a read.
