An excellent list of airplay enabled apps - although this was out a bit before the current Apple TV, I'm finding that these are some of the highest rated apps on the store with some very cool video capabilities.
For example, the free ShowMe app combs your networks and serves up video that your friends are watching -- not to your ipad (although that is possible) but to your TV that is enabled with the Apple TV. I'm finding the Apple TV higher quality than my Roku box, although I'm keeping my Roku box because it has Amazon and my Apple TV does not. If you get an Apple TV, make sure you set up Remote and download some of these apps.
