I have a second-generation Apple TV set-top box, and really enjoy using AirPlay to stream movies from my iPad to my 42-inch HDTV. It's fun how simple it is. If you have an iOS device and Apple TV on the same WiFi network, you simply start playing a video and tap a button that gives you the option of playing the movie on your TV instead of your iPad. If you need to go out and want to continue watching the movie, you simply toggle back to the iPad and continue watching.
