Hello all, I've never had an Apple tv before. I have a mbp and an Iphone 6plus, i'm looking for something to add to my tv. My main use would be netflix, spotify and streaming content from my phone / mbp. Do you think that it is worth to pay 130/150 for an apple TV 4 having the 3 at 50$ ? Which are the main differences ? (apart from the remote and games) Are they supporting different tvOS versions?
