MacHeads, free, full movie. Thanks to Norm.
(Unfortunately it's Hulu and can only be viewed in the US. I could watch it at Lovefilm.com because I'm a customer there. But I don't know if it's hosted for free any other places.)
It's amazing how this documentary divided the audience. Many hated it, but for wildly different reasons. I quite liked it, it had a succinct history of Apple and the Mac Community, and it featured people I know and like, for example Shawn King, Adam Engst, and Andy Ihnatko. I think it makes many good points too.
