If you're really going to use them for cut-the-cord TV, you should look into the Tablo. Terrific product with all the pieces.Can asterisk run on Android? Is its OS on an SD Card we can wipe. I would Love these for AllStar (Asterisk Based Ham Radio) would make a Great Radio-Less node for less tahn a RaspberryPi3.
Picturs don't show an SD port so I would be hesitant, not to say I won't but... Although if they did work I'd buy 6 (one for each TV I have and then a few extras for Ham Radio related projects.
