The mastermind behind Apple sheds his low profile and steps forward to tell his story for the first time. Before BlackBerries, PalmPilots, and laptops that fit snugly into briefcases, computers looked like big, alien, vending machines. They had large screens, cryptic switches, huge boxes, and odd lights. But in 1975, a young engineering wizard named Steve Wozniak had an idea: What if you combined computer circuitry with a regular typewriter keyboard and a video screen? The result was the first true personal computer, the Apple I. Widely affordable and easily understood, Wozniak's invention has been rapidly transforming our world ever since. Wozniak's life--before and after Apple--is a "home-brew" mix of brilliant discovery and adventure, as an engineer, a concert promoter, a fifth-grade teacher, a philanthropist, and an irrepressible prankster. From the invention of the first personal computer to the rise of Apple as an industry giant, iWoz presents a no-holds-barred, rollicking, firsthand account of the humanist inventor who ignited the computer revolution. 16 pages of illustrations.
