The video they played at WWDC 06 before the keynote started.

www.freecomputertutor.net offers an introduction video to the free openoffice.org office software suite. This software may be used as a substitute for MS Office software and can run on the following operating systems Sun Solaris, Mac OSX, Windows, and Linux.

By request, here is when Steve Jobs introduced Mac OS X for the first time ever. I edited the video myself to show the very best moments of the presentation & split it up into 3 parts on account of youtube’s bogus time limit.
