> That's more a criticism of "crappy Android boxes" rather than a praise of builtin TV applications. The latter are still barely usable and quickly become obsolete (with updates stopping 1-2 years down the line), compare that to a good Android box like Nvidia Shield.

Sorry, but this is just no longer the case. Even my neighbour doesn't turn on his Nvidia shield anymore because his Samsung TV OS is good enough and the Youtube/Netflix apps are fantastic. Samsungs OS is where the dominant marketshare is so the apps are great.
