Get the NVIDIA SHIELD instead of a tablet?

200 bucks and it comes with a controller, and it works with Logitech universal remotes. It has IR, instead of using bluetooth like the Fire TV.

Only problem is Kodi isn't in the Play Store, no idea how to sideload apps on android TV.

Sideloading might be the same as in Android.

Why would you need the 500 GB version? It has two USB 3.0 ports, so you could get a 1 TB external drive or bigger and plug it in. No need to pay another hundred bucks right away.
