I use a Mac Mini for my htpc. Give me control over that thing, or a superior applets via voice and i would buy a $300 siriEcho.
It still amazes me that not one company has gone for the full batman computer setup for the home yet. Amazons echo doesn't communicate with the firetv... and even if it did it's limited to video services mostly. Apple TV is limited the same way.
Chromecast feels like the closest, but I want full voice control with correctly designed switching of focus. Examples:
"Siri, show me what's playing" *tv turns on, shows me album artwork and song info"
"Siri, play the next episode of handmaidens tale on Hulu" *stops music, switches to Hulu app, stars next episode
"Siri, show me a map to Disneyland" *pauses video, loads up web page with google map to Disneyland
"Siri, thank you" *closes page and resumes video
"Siri, FaceTime my wife" *pauses video, Apple TV cam turns on. Calls wife and I talk to her through the tv. Call ends, video resumes
Basically want a full demo of use similar to the very first iPhone demo that jobs showed, where it seemingly switched app focus from music to maps to internet to phone. Just now with Apple TV like device, from video, to web page pop ups with info, to maps, to video calling, to music, etc. Cuz the execution with how seemlessly it switches to the correct task is what matters
