"In schools," says Steve Wozniak, the inventor of the Apple II, "the life span of a desk is 25 years, a textbook is 10 years, and a computer is three years, tops. Which of these devices costs the most to buy and operate? Why, the PC, of course. Which has residual value when its useful life is over? Not the PC--it costs money to dispose of. At least books can be burned for heat. Until technology slows down enough for computing platforms to last long enough to be economically viable, they won't be truly intrinsic to education."
