For travel to places that have flat screens with HDMI inputs (just about everywhere these days), what is needed to take an ATV2?
1. ATV2, iOS device (iPad2 or iPhone4S)
or
2. AT2, iOS device (iPad2 or iPhone4S), and wireless network device such as Airport Express
We do have the 30 pin dock to component plug adapters which have worked great in the past to get video from our iOS devices to TVs, but I would like to know how I can take advantage of an ATV2 in a travel setup.
