We have iPhones, iPads, and third gen ATVs in our house. I'm trying to decide whether it's worth upgrading the two ATV3s at this time. We have satellite TV and are not ready to "cut the cord", so for us the main drivers to upgrade would be: Performance/Ease-of-use: I would like a much more responsive UI, quicker movie loading and fast forward/rewind, easier browsing of media in the iTunes store, and much improved AirPlay. With AirPlay, I now experience long loads, glitches, and other issues. AirPlay has never been fully trustworthy for me. My router is an Airport Extreme, which I purchased specifically to make AirPlay work better (it helped but did not solve the issues). Sending 1080p video from my phone is particularly slow. Casual Gaming: I would like a quality casual gaming experience for the family. Reduced need to reboot: I have to reboot my ATV3 every month or two it seems, usually to fix an AirPlay issue, get Netflix to fully load, or get iTunes thumbnails to show up. It's annoying. For those who have jumped in already, how do you find the ATV4 measures up to this criteria? I know it's a new product and needs time for updates. I'm willing to jump in if it is mostly there now and trust that Apple will keep improving it. I bought the Apple Watch at launch, to give you an idea. It's not perfect but it's improving and I've been happy with my purchase.
