If Apple doesn't immediately revamp their entire computer line and make it truly cutting edge, they've got less than two years. This iPhone debacle is the perfect storm to make an entire market blink and realize that iCrap is just that, iCrap. And overpriced. Apple's cutting-edge cachet is gone.
Fad toymakers do not survive long term. This happened to all the great organ companies when they tried to compete with the first Casio "dimestore" keyboards. The only ones that survived (and survive to this day) make instruments that START at five figures. All the ones that tried to make cheap crap to compete with Casio vanished one by one, and in the order they tried to chase after Casio.
