I really enjoyed the "Welcome to Macintosh" documentary! Thanks Brian Stone for recommending it and ordering me a copy. This documentary gives you an inside look on how the Mac came to be as well as some stories and interviews that I had not yet heard. It's worth owning, but if you're more of a rental kind of person, you can now either buy it or rent it on iTunes.
Watch it on your computer, your iPhone, your iPod or your Apple TV.
