I freaking hate Smart TV's. I wish a guy could just buy a high quality display panel. I don't need (and most others don't) any TV tuner, speakers, or other crap built in. Hell, just 1 HDMI port is all is needed nowadays. Whether you're running an AVR or just a streaming device. OK, maybe a few of those could be justified.
I still have a 10 year old Sammy LED that works fine, but the smarts are junk by now. So I buy a ~$50 Roku to replace the extra $400 I had to pay at the time for the "Smart" TV.
Its kinda like those stupid companies that combine Modem/Router/Wife AP into one appliance. So that way if one part fails, you have to replace the whole thing. Maybe somebody will make a Fridge/Micro/Oven combo unit. So when my Micro fails, I have to buy all three again.
