U still buy a box if u do serious local playback of the highest grades video as no TV player can offer same. Not any box but the premium ones.

For online streaming incl netflix, Disney, etc. Google TV TV does a great job, can forget the box.

Android TV... I hv a TV on atv 8 yrs old, still humming good, all gud with Google approved apps.Dunno when atv will be phased out. 10 yrs will be ok!
