Hello everyone. I am considering purchasing an Apple TV. I saw somewhere online that it would only work with TV's with either 720 or 1080 pixles. Is this true, or will it also work with other HDtv's? Are these numbers,just the ones that give you the best picture? I have one TV that it should work with, but I'm not sure about the other two and I want to be able to move it around from room to room. Also, I saw that there are 3 generations of Apple Tv's, but it also looked like there were different models within each generation. So, what is the most current generation and model that has the updated software. I looked on the Apple website, and all my questions were answered accept these two. Also, any other information that you feel is helpful would be greatly appreciated. Also, to those of you who own these, are they worth buying? Thanks!!
