Mirroring as an option is amazing, I have wanted this since the first iPhone! Does that mean things like Netflix and Hulu Plus can then be watched on a tv?
What about AirPlay? I have an Apple TV (ATV2) which is connected to my HDTV via HDMI. Would that allow me to wirelessly send 1080 video from my iPad1 to my HDTV? Would it be better than getting this HDMI adapter?
