Just noticed this while watching the Grammy's. Colbert whips out his sleek new iPad (envy!) and I noticed that the homescreen flipped when he went from horizontal to vertical. http://www.engadget.com/2010/01/31/stephen-colbert-has-an-ipad/ The video shows this, at around :15. Also, he holds it sideways as he "reads" the nominees. Could he have been looking at the homescreen?
