Disruptive technologies change history, and the original iPod, iPhone, and iPad are already collectible. The classic iPod put a thousand songs in your pocket and upended the music industry. The iPhone sent the "CrackBerry" on a downward spiral, kicked off the apps economy, and ended up in the pocket of every other middle-schooler. The iPad is arguably reinventing the concept of personal computing.
