Official streamers all have the same problem
Because of all the nonsense rights we have particularly in the UK I can't buy a box that will let me watch content on, I have to have a Sky box to watch somethings on, that requires a subscription, then I need a Netflix subscription, then I fancy watching the new Top Gear stuff, that means an Amazon subscription, oh and I want to watch the news so I need a BBC subscription/license, the list goes on.
I just want an internet connection into my house then a box that will let me watch any TV programme or film I fancy, but the only way to do this is to either have a house full of DVD's and BD's or use something like Popcorn Time, download everything I want via KAT or wherever then set up a PLEX machine and stream it to my RP.
With the ATV4 having the App Store native then if I can install Plex or PT on it without having to jailbreak it then I'll buy one on launch day as other than as a remote screen the ATV3 wasn't much use to me.
