When you watch the commercial about photo stream on Tv. It shows someone taking a photo on the camera and it instantly appears on the iPad/apple tv. This is not working for me, I will take pictures when I'm traveling to show my wife and kids and sometime it take hours to days for the picture to appear. Why is this? My current photo stream has 350 pictures, we have two iPhone's, Two 4th gen iPod touches, one new iPad and apple tv under one account. Any thoughts? THank you
