<<...But for Mac fans, the holidays don't end on New Year's Day. We all look forward to Macworld Expo in January, when Apple pulls back the curtain on its latest cool stuff. And for the first time, we'll have an official Google booth at Macworld. If you're at the show, we hope you'll drop by and say hi. Until then, enjoy your holiday season, and we'll see you in January. >>
  

I could have sworn they were at the 2007 Macworld expo too. I was given a Sketchup CD from someone who attended the expo.
