Please let us know what the fireTV stick is like. Was also thinking about getting one for the older folk when they come around, they think what we do with the chromecast is some sort of evil sorcery and refuse to switch on the telly when we're not home. They sit en stare aimlessly at the black screen for hours while drinking tea. Otherwise I'm looking at perhaps a Nexus player since you can also cast to it.
Can these remotes on the fireTV, nexus player, shield etc switch the TV on and off... I think that's their main problem. Since the chromecast automagically switch on the TV when you cast to it, they assume the TV can only be switched on with magic and spells since they don't see us using some sort of button.
