The best TV set box on the market right now is hands down the Nvidia Shield, it's simply awesome. Not only does it not have any of the restrictions that the Apple TV has like, no 4K output, no ability to use USB accessories like; game controllers (great for special controllers used for emulatorsm i.e. N64, SNES, Sega), hard disks, web cams (I have a 360 degree camera that follows me around, super cool), keyboards with built in trackpad (a must have if you surf on your TV which if not, why, it's great), no SD Card slot, etc. It can't be used with special software like Kodi or even be turned into a desktop computer by installing Linux on it, which by the way, works fantastically, there is even native GPU drivers. There is also the Nvidia games streaming software, which is simply bitchin, PC games that have been ported specifically for the Shield brand like Doom 3, Crysis 3, Half Life 2, Portal and the ability to stream games from your PC directly. It's also the fastest on the market and of course handles 4K. Before you guys jump in about the lack of 4K content, 40% of the shows I watch now are being streamed in 4K (check out Amazon's Ultra HD), I have over 80 films now in 4K, with more coming each month. This notion that 4K is still 2 - 4 years away is absolute BS, maybe for broadcast but online streaming service are quickly adopting this format and in just 6 months would have tripled the amount of media available for it.
