Why did Apple discontinue the PowerBook 2400?
While they discontinued it in North America, in Japan they introduced a new model, the PowerBook 2400/240. The reason for discontinuation is primarily poor advertising. They never marketed these models aggressively as they did the 3400 and 1400. You had to know the 2400 existed by other means, otherwise you’d rarely hear about them. (Sounds just like the Newton MP 2000, which I also think is a great portable computer).
