I personally dont see the point in these aside from just putting it on a larger screen than your computer, since you still have to subscribe to all the apps (as in pay for them) anyway.
At that point, just get the cord hookup that links your computer to the TV. The computer (or tablet) has to be fairly recent in make and the TV has to be HD if you want to make your life easier. That way you can find whatever you want to watch on your device, free or otherwise, and watch it on the big screens for like 20 bucks.
