I moved from the 3rd gen ATV to the 4th at the time of release. There are plenty of things that I like about both systems, and feel that they are probably still among the best streaming solutions around. In general, I'm usually a pretty huge apple fan / promoter. But, this thread is for complaints. * The physically symmetric remote. There is no substantial physical cue for feeling the difference between the remote being held right side up vs. upside down by touch. This leads to frequently experiencing an exit to the home screen when a pause was intended. * Touch scroll is overly sensitive to false contact. Just picking up the remote incorrectly can lead to the viewing position scrolling wildly across 20-30 minutes of content. * Siri seems buggy. It seems like it should be one press and then talk, rather than hold to talk (just a preference). Instructions seem to get truncated and misunderstood (with wildly out of context responses) more often than not. Simple things like "turn on subtitles" often don't seem to work. Once Siri responds with a non sequitur, the procedure for discharging the response and getting back to the main view has seemed counter intuitive. * Aspects of the interface that seem like they should be global are not always propagated effectively into all similar downstream apps. In particular, the Yahoo Screen app is really terrible (I realize this isn't necessarily Apple's fault), with non-standard response. For example, it doesn't provide the inset content preview window while scrolling, which seems like it should be an absolute default. That app in particular also makes strange volume changes for me after pause and resume. * The text entry system is unbelievably bad, with no ability to use the keyboard on an iPhone. * The remote app for iPhone is non-functional with the 4th gen. This is apparently being worked on, but should have been release day ready. * The implementation of login for viewing on apps with a coupled TV subscription is problematic. Again, this may be a burden imposed by the content providers, but it is still a problem. It should be a single login to the content provider, which then provides a list of available apps with permissions. Instead, each app provides its own online code to be entered individually. Furthermore, the SuddenLink (again this may be a particular problem upstream that Apple is not directly responsible for, but it is still a bug in the ecosystem that gives the whole works a feeling of incompetence) provider login is generally not working for me. Actually, it claims to work, but then doesn't, which is worse. For example, if one is using ABCGo to watch "Agents of Shield" (insert your show here) then there is generally a one-week delay lock for new episodes, unless you are logged in. I am logged in, so the episode shows no lock. But, when I try to play a new episode I instead get a cryptic internal error "noAuthz". * Scrolling is still not as smooth as I hoped. The number one complaint with the 3rd gen was that rewind was difficult, and not easily metered between fast/slow review. Also, there was virtually no caching to allow review of just watched material without rebuffering. This is much improved in the 4th gen, but still not ideal with regards to seamless backups and finely grained rewind/fast forward. The little inset window is a helpful addition, but the process is still not as intuitive and natural and seamless and responsive and precise as I had hoped. Again, there are plenty of things I think that they got really right, but these nags are limiting my satisfaction with the system overall. Anyone else having a mixed response to the new unit?
