A list (with pictures) of some of the times Apple didn’t get it right. Of course, the definition of not getting something right is often in the eye of the beholder (or user), and items like the Newton, Apple IIc and Lisa (all of which I’ve used) all contained elements that contributed to better designs in the future (for Apple and its competitors). I think the MacBook Air might be in this category of a niche-product that helps stimulate all sorts of developments down the line, independent of how successful a system it is in its own right.
