The anatomy of Apple design
Cult of Mac has found this great video (below) that shows the history of Apple through CGI. It was actually posted in 2010 to pay tribute to the initial iPad's release.
The video doesn't include products like iMacs, iPods and Nanos as they wanted to focus on products that they believed related better to the iPad.
