What are some Macworld highlights through the years?

Question: Steve Jobs has recently announced the iPhone at the Macworld Conference. It seems that major Apple product announcements are always made in this event. Do you have a link showcasing Macworld Expo highlights and product announcements through the years?

I found a German site that lists Macworld highlights from 1983 to 2004. Missing highlights there were from 2005 to 2007 so we will just include them here.

2005 - Mac Mini and Ipod Shuffle
2006 - iMac and Macbook Pro with Intel Core Duo chip
2007 - iPhone
