forget "smart" TV's that spy on you
just get a chromecast stick for $35-40 and it'll be a lot smarter and better integrated with your tech.
edit: my friend got the 55" not the 49" ... went in thinking 49 but paid $100 extra for 55"
pretty impressed with it too for $500. reviews say audio sucks but i'm not audio snob and we thought the audio was pretty decent.
you want TV's that have at least 4 HDMI ports IMO...after plugging in TV box, game system, chromecast, etc...ports dry up fast...
