Meh, still hanging on to my ATV3, haven't felt the need to upgrade. Disappointed that Apple couldn't make Job's last great idea, the mother of all TV idea come to fluition.
(first of all, thanks for commenting!) So, I can't blame you, because I too really wanted Apple to reinvent TV and not just release a Roku with a prettier interface (god that thing is ugly).
But, as someone who owns both, I would rather move my ATV4 between rooms than dedicate the ATV3 to a single screen. One big perk of the 4 over the 3 is that more content is available, as nobody's developing channels for the ATV3 anymore.
Still, probably not worth it if you have all the apps you need.
