Yeah, the price difference is minimal I was just curious if people really needed the extra capacity. For that price I suppose if it's not needed it probably will be in the future and it'd be good to be prepared.
the 4k upgrade is the only one that matters. Unless you plan on using the Apple TV as a game console, the storage doesn't do much. I have 4 in the house, one is a 64, but I have no idea which at this point.
