The UI seems to gotten much more sluggish over the last year or two. I have a 500 Mbps internet connection, but speed tests in the TV's browser measure only 40 Mbps (on Wi-Fi or Ethernet). The TV's apps load images and data as if I'm on a 2G connection.
The Amazon and YouTube apps hang if I turn the TV off and try to resume playback later. I have to switch to two other apps and then back to Amazon to force the app to crash. Then I can launch it again. And sometimes the only way to exit the Netflix app is to power cycle the TV.
They do, but from what I understand you'll pay more for such panels. As I understand it they're intended for commercial use.
That actually sounds like the dream.
Plan on getting one with a stick PC.
I used to joke with my brother and turn his TV on/off, he went crazy thinking the TV is broke.
