Being an authorized dealer for AppleTV, Samsung, and Sony, with many installs, set-ups, and trouble-shoots under my belt: The best video/audio performance is noticeable (to a professional) via Sony's OLED televisions through the built-in app. If the AppleTV app is not available, then the TV is simply too old. As far as support, I have not found Apple's to be any better or longer lasting than any other brand. Connecting an external device to any type of component will necessarily introduce additional processing, which degrades performance, although Sony's current ability to make anything look superior is not matched at this time. Usability is undeniably in Samsung's corner, unless, of course you are an Apple "fan"; all things Apple will perform better for you, until they are purposely made obsolete for their next offering. Currently, the widely used, and lauded by Apple fans, AppleTV touchpad remote has been replaced by one with hard buttons for people with more common (not to be derogatory) sense. Personally, I prefer AppleTV's older GUI which was not capable of pushing as many unwanted offerings on the user. Data-mining is no less intense on Apple products as any other. Likewise, the only reason Apple products are not hacked as much as others, is because they would rather spend their baseless lives on a larger audience. For Apple fans, usability will be smoother on anything Apple. Sony has also had some serious glitches with their network interface, which appears to have been fully corrected, so far. For some of my Samsung users, I have been able to get The One Remote to control full racks of A/V equipment along with all peripheral devices, including outboard AppleTV's. I don't recommend this, however; I charge by the hour.
