The incremental steps that Apple has been taking with the iPod, iPhone and iPad have been fine, Bushnell says, but not enough to prove the company is still thinking differently.
"To really maintain the cutting edge that they live on, they will have to do some radical things that resonate," Bushnell said. "They probably have three more years before they really have to do something big. I hope they are working on it right now."
Bushnell is still keeping busy himself. When he isn't writing, he is running his latest startup, Brainrush, which is trying to turn the process of learning into a game-like experience. He says he hopes to fix an educational system that he believes is "incorrect, inefficient and bureaucratic — all the things you don't want to see in your workforce of the future."
