So since this post last year, I've had substantial time with this product (
AirTV Player) and yesterday added this product (
AirTV) to my arsenal.
The airtv_player has really great integration with Sling TV and my local channels. They also recently added the ability to hook up a portable hard drive to pause/DVR local television and it's been fun having it record every episode of old syndicated shows of interest, and still having 90+ hours left on the hard drive to record more.
The airtv_player is also powered by Android so I can access SOME of my other cord cutting apps like Netflix, HBO Go, and Pluto. However, updates of the player are very few and far between so there are apps that don't even come up as available because they're not compatible with the box (i.e. Amazon Prime video).
The advantage of airtv is that you can hook the antenna up to it and once logged into your Sling account, can watch your local TV channels from every Sling enabled device...except for the airtv_player. Also at that point, you lose the ability to be able to DVR local channels because you no longer have an antenna hooked up to the airtv_player and airtv does not currently support DVRing.
There also are a few lag issues when watching the streaming local channels -- I haven't had enough time with it yet to see if it's just a antenna signal issue, or related to a lot going on on the screen, or something else.
