I am having BlueSky installed in a week's time. In the meantime, I have a question. I have been using Apple TV because it accesses Netflix and You Tube -- and also to display on my TV the photographs which reside on my iMac. I don't really use Apple TV for any other reason. If BlueSky can do that, I am wondering why I need to bother with Apple TV at all. Maybe I'm missing something. Apple techie, please respond?
