XBMC renders itunes useless. Never gonna happen, if it does I would buy one.
Why would it? I, like a majority of the population, have no interests is pirating or ripping DVDs. You are speaking for a tiny segment of the market.
XBMC is so much more than just a piece of software to use for pirating. XBMC/Kodi is the best media player out there imo.
Which serves a small niche market.
Choice is good. It would be nice to have access to all the content on kodi.I couldn't imagine why I would want Kodi or Plex on an ATV. This is especially true when there are superior players like NVidia Shield TV for 200-300 bucks that do far more. The only thing the latter doesn't do is get caught in the iTunes Store web.
ATV is a brilliant front end for iTunes Store and now what will be the apps store offering.
playing 4k movie on Kodi/Nvidia Shield using 1Gb ethernet is smooth but stuttering on AC wifi.
Kodi is officially on Google Play store (not Amazon). but I doubt apple would approve it. though I love to have it on ATV 4.
