When it launched the new Macbooks, Apple announced that they would sport a new digital video output connector, known as Mini DisplayPort. What Apple failed to mention, however, is that those connectors allow movies studios to force the computer to authenticate any external monitor before allowing playback of programs purchased or rented from the iTunes Store (Microsoft's Windows Vista does something similar). In other words, the HDTV monitor or projector that worked for you yesterday, won't work with your new computer tomorrow if Hollywood has embedded a flag in the iTunes content you paid for. -- "As we open our newspapers or watch our television screens, we seem to be continually assaulted by the fruits of Mankind's stupidity." -Roger Penrose
