Christopher Bonanos draws some fascinating comparisons between the two companies in Instant: The Story of Polaroid. From an excerpt:

Both companies specialized in relentless, obsessive refinement of their technologies. Both were established close to great research universities to attract talent (Polaroid was in Cambridge, Massachusetts, where it drew from Harvard and MIT; Apple has Stanford and Berkeley nearby). Both fetishized superior, elegant, covetable product design. And both companies exploded in size and wealth under an in-house visionary-godhead-inventor-genius. At Apple, that man was Steve Jobs. At Polaroid, the genius domus was Edwin Herbert Land. …

At Polaroid’s annual shareholders’ meeting, Land often got up onstage, deploying every bit of his considerable magnetism, and put the company’s next big thing through its paces, sometimes backed by a slideshow to fill in the details, other times with live music between segments. A generation later, Jobs did the same thing, in a black turtleneck and jeans. Both men were college dropouts; both became as rich as anyone could ever wish to be; and both insisted that their inventions would change the fundamental nature of human communication.
