I purchased a Chromecast with Google TV to use with my Sling TV subscription. Was hoping for a better UI then the one on the FireStick/Cube. Generally the steamed channels work OK but the OTA channels (using AirTV Anywhere) have major buffering problems. There are no buffering problems using the Firestick. Contacted Sling and they are staying that the Chromecast dongle is not a supported platform so I'm out of luck. You would think that if Sling TV allows their app to be preloaded on hardware they they would make sure it works halfway decently.
