I've owned every version of Apple TV (including the clunky 1st gen). Love the 4. I think my favorite things so far are: The new remote (totally did not expect to like it) The UI is fast The apple tv controls my TV without me setting anything up My TV remote (Sony) controls the Apple TV without me setting anything up 802.11AC wifi There were definitely a few bugs so far. Netflix got really quiet for a bit, NBC wouldn't let me activate and Hulu lost my credentials once already. I saw some posts about home sharing movies buffering. I played two iTunes 1080p movies (about 15 mins each) and did not experience that issue. Hopefully it holds up. Anyway I'm definitely getting another. Super happy with the purchase. BTW I don't know if you guys noticed but every TV app supports Comcast now (at least all the ones I downloaded).
