I have to say that it wasn't as excited as people had anticipated. There was no iPhone Nano, no Mac Mini.
The features added to iPhoto was pretty cool though. It attempts at facial recognition, using GPS data embedded within pictures (JPG). Besides this there were several other announcements made but again nothing as exiciting to mention here.

Just one more thing, Apple Ended their last Macworld with a statement "The Best is yet to come"
