Why? So we could all huddle together and feel all warm and nostalgic and have a moment of closure? What has Steve Jobs ever done to give you the idea he would step away from something like MacWorld with any nostalgia or ceremony? Was it when he slashed through Apple's product line-up when he returned to Apple? Was it the clearing out of the old Mac archival stuff from the Apple campus? Was it the jettisoning of all the beloved Mac-isms from the OS 9 era? Was it his complete lack of acknowledgement of any of Apple's supposedly significant anniversaries? The man clearly isn't as nostalgic about these things as some of his customers are..
So much anger, young padawan. This is why I think there will be a send off.
