GOOD OPTION, BUT NO MIRACAST!
Advantages: Fast boot, nice apps pre-installed (modpro, youtube, playstore...). I've tested it and works fine with kodi (except for shutting it down, very slow I don't know why) and for the other tv apps. For gaming I've tested MAME4DROID and MAME4ALL and its great with both of them (using a bluetooh Mi Pad it's a good idea for that).
Limitations: Movistar + original app and account crashes if you try to rewind/forward the streaming. The lower navigation bar could be hided, but you won't be able to turn it back until you restart the device.
